editor's comments:- August 2013
- Silicon Motion is a supplier of
bit per cell flash / TLC and the company also offers products in the
SSD on a chip market.
Silicon Motion's recent SSD controllers have aspects of
DSP technology. It appears in their case they use LDPC with variable
strength codes in combination with other techniques.
Iin June 2008 -
announced a new family of flash
SSD controllers which
enable oems to mix and match MLC and SLC chips in the same drive.
controller can analyze the incoming files from the host and intelligently move
frequently accessed data to SLC NAND and non-frequently accessed data to MLC
NAND. With this innovative hybrid architecture, the SSD system cost is
significantly reduced to a level comparable to a pure MLC-based SSD, while
endurance is significantly enhanced and comparable to a pure SLC-based SSD.
financial report Silicon
Motion's President and CEO, Wallace Kou said - " The NAND flash
industry has been increasing the output of 3 bits per cell MLC because this type
of technology is a capital efficient way for NAND flash manufacturers to
increase capacity without significant capital expenditure. These new 3 bits per
cell MLC NAND flash are very difficult to manage well and requires significant
advanced controller technologies. Our clear leadership in 3 bits per cell
controller technology validates our strategy of investing in cutting edge R&D
in order to bring new products to market ahead of our competitors. ...Our SSD
controller shipment growth (in the past quarter) was flat sequentially, but
grew almost 300% compared to a year ago, and revenue from these products
continues to account for almost 10% of our overall corporate revenue."

which I learned about from Jonathan Bruce
- who suggested it for my article -
Speed and Strength Metaphors in SSD brands - because - he said - the "Ferri"
prefix means "strong or durable". |
31, 2014 - in the same product family - Silicon Motion is now sampling a
high performance 6Gb/s SATA FerriSSD - the SM659 (8GB to 64GB capacity, with
80,000 random IOPs, and 30K Program/Erase (P/E) cycles) - which fits into a
90-ball BGA package measuring just 16x20x2mm.

SSD controller which supports MLC, TLC and SLC NAND flash from all the major
NAND suppliers. |
supports 4 channels of NAND flash devices with up to 8 CEs per channel and can
enable sequential reads upto 540MB/s and writes upto 410MB/s. Random IOPS
performance is upto 80,000 read IOPS and 75,000 write IOPS. Average power
consumption is 60mW. Security
features include AES 128/256, TCG and Opal full-drive encryption compliance.
comments:- in a paper this week at the
Flash Memory Summit -
Efficient LDPC DSP System for SSD (pdf) - Jeff Yang Principle
Engineer, Silicon Motion discussed how its adaptive LPDC DSP techniques which
supports variable parity lengths provides 3x better
than traditional BCH.

announced imminent sampling of a new
controller - for consumer handheld products. |
The SM2703 is a
single-channel, SD 3.0 UHS-I (Ultra High Speed Phase I) card controller with
superior support for the vast majority of NAND flash, including 2y-nm, 1x-nm and
1y-nm TLC and MLC which delivers up to 95MB/s and enables full HD video
recording capability by digital cameras, smartphones and other mobile devices on
both Class 4 and Class 6 SD flash memory cards using cost-effective TLC NAND
"We've already had tremendous success in the UHS-I
market since we introduced our first UHS-I controller 2 years ago - which was
used by most of the world's leading flash card brands" said Wallace Kou,
President and CEO of Silicon Motion.
"Our solution was widely
adopted because it was high performance, cost-effective, and supported the vast
majority of available NAND components. Our new 55nm based SM2703 controller
is firmware compatible and is a cost-effective, flexible quick way to market
for customers who want to use the latest MLC and TLC NAND flash."
