Silicon Motion SM2246EN SSD Controller Supports Microns 128Gb 16nm MLC NAND

Silicon Motion Announces SM2246EN SATA 6Gb/s SSD Controller Supporting Microns128Gb 16nm MLC NAND

Taipei, Taiwan, June 3, 2014 Silicon Motion Technology Corporation (NasdaqGS: SIMO) (Silicon Motion), a global leader in designing and marketing NAND flash controllers for solid state storage devices, today announced that its SM2246EN SATA (6Gb/s) client SSD controller now supports Microns 16nm 128 gigabit (Gb) MLC NAND flash, ideal for high performance, high capacity SSD solutions up to 1 Terabyte.

SM2246EN offers the best performance and power combination of four channel SATA 6Gb/s client SSD controller in the market, delivering even better performance than most 8-channel SSD controllers with substantially lower power consumption. Using Microns 128Gb 16nm MLC NAND, the SM2246EN delivers up to 538*MB/s sequential read performance and 450*MB/s sequential write, as well as up to 67,000* random read IOPS and 65,000* random write IOPS. In addition, with Micron 128Gb 16nm MLC NAND, the SM2246EN delivers ultra-low power consumption, equating to about 30**% lower than the average power consumption of other SSD controllers.

We are pleased to announce that we have delivered and qualified the SM2246ENs firmware and reference design for Microns 128Gb 16nm MLC NAND to many of our customers. said Nelson Duann, Vice President of Product Marketing of Silicon Motion. SM2246EN currently is in high volume production supporting multiple MLC and SLC NAND from major NAND suppliers. By supporting Microns 16nm 128Gb MLC NAND, our customers have more flexibility for their high density, high performance and power efficient SSD solutions.

“Micron has seen tremendous interest in our 128Gb 16nm MLC NAND because it delivers a unique combination of capacity, quality, and performance.” said Paul Petersen, director of marketing for Micron’s NAND component division. “We’re pleased to work closely with Silicon Motion’s expert controller developers to enable a compelling storage solution for high capacity, high-performance and power-efficient devices including PCs, Ultrabooks, tablets and SSDs.”

Key features for SM2246EN with Micron 128Gb 16nm MLC NAND solution include:

• Ultra high performance*

• Sequential Read: up to 538MB/s
• Sequential Write: up to 450MB/s
• 4K Random Read IOPS (Q32): up to 67,000
• 4K Random Write IOPS (Q32): up to 65,000
• Ultra Low power consumption Average power consumption: 56mW (Intels target**: 80mW)
• DevSleep mode: < 2mW (Intels target: 3mW)
• Slumber mode: 21mW (Intels target: 30mW)

• Ideally suited for both client SSDs and NAND-cache drives
• Proprietary, configurable ECC engine allows for consistent data throughput and performance throughout the entire SSD lifecycle
• Able to support both commercial and industrial grade requirements

The SM2246EN with the Micron 128Gb 16nm MLC NAND will be showcased at COMPUTEX, being held June 3 7, 2014, at Silicon Motions Private Suite in the Grand Hyatt Taipei.
