Toshiba's semiconductor business rescues company
Editor:- January 25, 2017 - Toshiba was featured in the mainstream news media last week due to losses by its US nuclear power business which had been responsible for halving the value of shares in the company. Reports that Toshiba's financial fix centered around selling part of its semiconductor business to Western Digital got a good reaction from markets.

is Toshiba salami slicing its memory heirloom?
Editor:- February 14, 2017 - Toshiba has today, again, topped mainstream media tech headlines due to the resignation of the company's chairman. In recent weeks - were I so inclined (to fan the flames of rumor) - I could have inserted some story or other about the sale of Toshiba's semiconductor business in this news page every day.

Instead I came to the conclusion that the real story was that there probably wouldn't be a single big story because the sale of the entire memory systems business to a single buyer (most likely another memory or SSD company) would inevitably introduce a delay due to antitrust hurdles. And Toshiba needs financial bandaids now.

Therefore, what we've been seeing is a fragmented approach - which on linkedin I described as "salami slicing" the memory business heirloom. Western Digital got some - but no one will get it all quickly due to caution about the impact of regulator antiacid.

Toshiba was fastest growing SSD vendor in 2016
Editor:- March 8, 2017 - The flash business unit of Toshiba - which may be called something different depending when you read this - has announced that its SSD business was the 4th largest by market share and the fastest growing (year on year) in 2016 according to data in a report - Worldwide Solid State Storage Quarterly Update, CY 4Q16 ($40,000) - published recently by IDC.

who will make enough flash?
Editor:- March 14, 2017 - A fab capacity view of the flash industry's ability to meet demand for memory this year is presented in - Shootout At Yokkaichi - the NAND Industry at the Crossroads by William Tidwell, Semiconductor Analyst who regularly writes about such things on Seeking Alpha.

Among other things Bill discusses the state of production maturity within the major memory companies in their transitions to 3D and says:-

"Industry productivity is still low due to a condition that could be called planar overhang - that being the amount of planar capacity that must be converted as fast as possible to 3D, so the company can take advantage of the denser 3D process. Unfortunately, this conversion process from planar to 3D is basically like buying a house that has to be completely renovated and then finding out that load-bearing walls are involved - and the foundation has to be reinforced."

The article's central theme is the imminent auction of Toshiba's flash assets, the main competitors and possible bidders, winners and losers.

Along the way you get a good feel for the investment and production dynamics which will shape the next few years of this industry. ...read the article

Toshiba's storage sale - update from Tom Coughlin
Editor:- April 4, 2017 - As previously reported Toshiba's memory and SSD business will be spun off to generate cash to plug losses in its nuclear generating business. A new article by Tom Coughlin, President Coughlin Associates - HDD Implications of Toshiba Memory Unit Sale - looks at the ramifications (no pun intended) for the hard drive market depending on which of the 10 or so potential bidders succeeds.

Among other things Tom says - "Selling the HDD unit along with the flash unit could be one outcome... The end result could be very interesting and create very strange bed-fellows." ...read the article

Sampling the engineering temperature in Toshiba's never never land
Editor:- April 30, 2017 - Speculation about who might become next owner of Toshiba's SSD and memory business continues... As I told you earlier this year I didn't expect this to be a short story, due to monopoly and other strategic interests.

The latest chapter in this flash novella comes as the number of buccaneers circling around the foundering wreck of Toshiba's corporate galleon and hoping to pluck the semiconductor gold IP fabs from its belly has reduced to 4.

Toshiba's memory business sale - tensions in the timing
Editor:- May 15, 2017 - progress updates about the sale of Toshiba's SSD and memory business have been part of the underlying news fabric during the first half of 2017. Tensions in the timing and conclusion of a prospective sales come from various causes:-
  • Toshiba needs the promise of a buyer as soon as possible to avert further downgrading of the parent company due to losses in other markets.

    An additional urgency is that the memory market was in a boom at the start of the spin-off process - with prices for memory rising.

    If the market changes back to oversupply or if other factors reduce the premium value placed on raw flash - before an acquisition is agreed - then the value of the business will be less.

    Delay therefore works to the advantage of a buyer and to the disadvantage of the seller.
  • The size and strategic nature of the transaction means that geo-political considerations and anti-trust hurdles will play big part in the decision process.

    If the potential buyer triggers a monopoly investigation in their own operating markets then delay in the acquisition is inevitable and could take upto a year.
  • A complicating factor is that Toshiba shares considerable flash wafer fab assets and IP with Western Digital which were part of arrangements evolved in partnership with SanDisk -which WDC acquired in 2015.

    In the current situation where Toshiba's memory business is for sale - there could be significant differences in self interest between WDC and any future owner of the Toshiba memory, SSD and HDD business.
In that context these reports about WDC's growing unease can be more easily appreciated:-
  • Nikkei Asian Review (April 21) - "Western Digital remains opposed to any sale of Toshiba's memory unit to a third party."
  • FT (May 15) - "Western Digital is taking its row with Toshiba to the International Court of Arbitration, as the US storage technology group tries to prevent what it claims is a breach of the terms of its joint venture with the embattled Japanese conglomerate."
Editor's comments:- It's clear that in the matter of who buys Toshiba's memory, SSD and HDD business the strategic and business self interests of WDC and Toshiba (parent company) are different.

But what would be best for the industry?

My own view is that if WDC succeeded in acquiring all of Toshiba's memory and SSD assets in 2017 or 2018 the effect would be to reduce the ability of the SSD market to be as competitive internally and also (although less important) reduce the ability of the SSD market to compete as aggressively with the hard drive market.

Another factor is the effect of competition inside the memory market and the effect on the emerging market for tiered big memory.

This is a market which is working to the benefit of users because there are pressures for flash to displace DRAM and a market climate which is nurturing the growth of new nvms which (although small in revenue terms now) could in the long term displace a fraction of the flash or DRAM markets.

In 5 years time such an acquisition (a major memory supplier being acquired by one of the two remaing hard drive companies) may not matter so much - because the SSD and memory systems market will have moved to new levels of efficiency and systems level utilization. But right now - I can see more negatives than positive for a competitive SSD market if such a deal were to go ahead.

Toshiba samples QLC says it will sue WDC
Editor:- June 28, 2017 - Here are 2 news stories about Toshiba.

Toshiba said yesterday that it is sampling the world's first 3D (64-layer), QLC (quadruple-level cell) flash memory to SSD controller makers for characterization.

The 768Gb chips are believed to be the highest density nvms currently available from anyone.

Editor's comments:- this is an extraordinary achievement for the nvm market. And you can judge how difficult it has been by comparing the actual timing to the earliest optimistic market expectations.

In February 2008 - Lane Mason - who at that time was at Denali Software and was one of the few people on the planet writing about such detailed matters - said - in the Denali blog - the industry expected the transition to 4-bit MLC cells, by 2012. So it has taken 5 years longer. (Lane is now at Objective Analysis BTW.)

The other Toshiba news story - Toshiba Misses its Deadline for a Deal for its Microchip Unit (NY Times) - is another episode in the much delayed (although not as much as QLC) serialization of the sale of Toshiba Memory - which many viewers had mistakenly believed had already publicly aired its season 1 finale. Among other things the NY Times article says this...

"Toshiba said it was suing Western Digital for about $1 billion over its attempts to block the sale of the chip unit..." ...read the article

WDC secures advance warning of Toshiba nand asset changes
Editor:- July 14, 2017 - Western Digital annnounced today it has obtained a court order to prevent Toshiba transferring its interests in jointly held nand flash assets without giving prior notice to WDC's SanDisk subsidiary (which shares some of these resources) "to ensure that the issue is preserved for arbitration."

A follow up story in Japan Times clarifies that the notice period is "2 weeks" and furthermore says "Toshiba lawyers have contended in court documents that any sale of the chip division was not expected to close until early next year, at the earliest."

more updates on WDC's dancing around Toshiba's memory business
Editor:- September 6, 2017 - here's a noise filtered reduced summary of recent news reports about the continuing saga of Toshiba's forced memory business sale.

Reuters (September 1, 2017) quoted extracts from a letter written by WDC's CEO to Toshiba - in August - which regrets the "significant ill will" felt by Toshiba caused by tensions between the 2 companies which have arisen as a result of the sales process.

Among other things WDC employees had been locked out of Toshiba plants and databases which had shared ownership in July according to a report by Silicon Valley Business Journal (July 19, 2017).

Coming up to date (September 6, 2017) Nikkei reported that WDC "has asked to buy some chip production capacity at fabrication facilities in Yokkaichi, Japan, in which it jointly invests with Toshiba" to guarantee its share of memory chips produced at the plant.

This nice legalistic distinction of owning machinery is described as a possible way to avoid delays in transferring funds to Toshiba which a would be inevitable due to regulator scrutiny if WDC were to purchase the company.

A fascinating noisier picture of how WDC and Toshiba have been dancing around these issues in recent weeks can be seen in this new (September 5, 2017) timeline on SeekingAlpha - WDC and Toshiba - Why This Time Is Different.

Toshiba says it will sell memory business to Bain led consortium
Editor:- September 20, 2017 - Toshiba today announced its long awaited decision about who it has chosen to sell its memory business to. It's a consortium led by Bain Capital using an acquisition cutout filter created for this purpose called K. K. Pangea. The transaction (worth about $18 billion) is "expected to close by the end of March 2018."

Editor's comments:- earlier reports which had speculated about the identity of members of the consortium named at various times Dell, Apple and Seagate.

Toshiba said in the above announcement "Western Digital has sought to prevent the sale of the interests of the joint parties (meaning Toshiba and WDC) to any 3rd party and Toshiba and WDC are currently engaged in litigation and arbitration."

An article on Bloomberg about the announced sale process says "The consortium members weren't named in Wednesday's statement to the Tokyo Stock Exchange."
