Founded in 2006 - Anobit is a NAND-based solutions provider. Its products range from MSP components to complete, enterprise-class solid-state drives. Anobit works closely with some of the world's largest NAND manufacturers, consumer electronics vendors and storage solution providers. The company has raised raised over US$40 million in investor funding. For more information visit

Who's who in SSD? - Zsolt Kerekes, editor

Apple acquired Anobit in December 2011 for a sum thought to be in the range $400 to $500 million.

This means Anobit has gone the same way as other SSD controller / IP companies such as Pliant and SandForce

As I said in my 2011 summary - there's a growing realization that "SSD companies are valuable."

Now that the deal is done - Apple customers will probably be more interested in seeing what they can find in Apple Insider's SSD page.

Another final Anobit article with an Israel / SanDisk people connection - by SanDisk focused blogger - Savo Lainen.

Anobit was a technology leader in adaptive flash care management & DSP IP for use inside SSDs.

editor's earlier comments:- April 2011

Anobit entered the SSD controller market in June 2010. Its main competitors are:- SandForce (for controllers) and STEC (for SSDs). Because these are the companies which are setting the agenda in the high IOPS part of the 2.5" SSD market.

I wrote about the problems in reading repeatable logic states from 3 bit MLC flash cells in my March 2008 article - Unveiling XLC Flash SSD Technology in which I said "In simple language - you don't always read out the same digital value that you wrote in."

Anobit says it uses DSP technology to filter out effects which can mask or distort the true logic state (which is inferred from reading an analog charge value back from the flash storage cell.)

While it's almost certain that other SSD companies have alo been using their own design tricks to get better results from this problematic interface - Anobit was the first SSD company to publicly talk about this aspect of SSD design in a systematic way.
Anobit mentions in recent SSD market history

In June 2010 - Anobit entered the SSD controller market with its announcement it was sampling SSDs based on its patented Memory Signal Processing technology which provide 20x improvement in operational life for MLC SSDs in high IOPS server environments.

Based on proprietary algorithms that compensate for the physical limitations of NAND flash, Anobit's MSP technology extends standard MLC endurance from approximately 3K read/write cycles to over 50K cycles - to make MLC technology suitable for high-duty cycle applications. This guarantees drive write endurance of 10 full disk writes per day, for 5 years, or 7,300 TBs for a 400GB drive, with fully random data (worst-case conditions).

First-generation Anobit Genesis SSDs deliver 20,000 IOPS random write and 30,000 IOPS random read, with 180MB/s sustained write and 220MB/s sustained read.

In August 2010 - Hynix Semiconductor announced it has selected Anobit's SSD controller technology to operate with its own 20nm class NAND Flash chips for use in a new SSD design.

In December 2010 - Anobit's chief scientist Naftali Sommer wrote an article - Signal Processing and the evolution of NAND flash memory (pdf) - which was published in Embedded Computing Design magazine. The article describes the role of DSP in improving the integrity of logic states read from flash cells.

In March 2011 - Anobit announced that it has commenced high volume production of its MSP2020 NAND flash memory controller in cooperation with Hynix Semiconductor. The MSP2020 controller enables the use of commercial-grade 2-bits-per-cell and 3-bits-per-cell NAND flash across all of the latest process nodes, within endurance- and performance-intensive embedded computing applications. MSP2020 controllers support up to 2 ONFI-compliant NAND interfaces to a host processor, and can support product configurations from 4GB to 128GB.

In April 2011 - Anobit announced it has licensed IP cores from Cosmic Circuits for several of its SoCs. The analog IPs which consisted of linear regulators, a power-on-reset and a silicon oscillator (with integrated clock multiplier) were implemented in 65nm CMOS process. These IPs were integrated into Anobit's flash memory controllers to enhance reliability and performance.

In September 2011 - Anobit announced it is sampling the fastest (yet) 2.5" SATA SSDs based on its own controller design. The new Genesis SSDs (upto 400GB) delivers up to 70,000/40,000 IOPS (4K block size) and 510 MB/s sequential read/write with non-compressible data using 2xnm MLC NAND. Anobit says its patented Memory Signal Processing technology elevates MLC endurance from 3,000 write cycles to over 50,000.

In December 2011 - industry rumors discussed the possible acquisition of Anobit by Apple for $400 to $500 million.

First you learned about SLC (good flash).
Then you learned about MLC (naughty flash when it played in the enterprise - but good enough for the short attention span of consumers).

Then MLC SSDs learned how to be good.

Now some MLC is much nicer than others. - When it's preceded by an "e" (extra-good). But it costs more.

But other people say you don't need the expensive "e" - because their controllers empathize better with naughty flash. (They really care about naughty flash being sent to bad block jail too soon.)

Is your head ready to explode yet?

It's going to get even more complicated.

flash SSD capacity - the iceberg syndrome
Have you ever wondered how the amount of flash inside a flash SSD compares to the capacity shown on the invoice?

What you see isn't always what you get.
