6Gb/s SSD controller supporting Micron’s 128Gb 16nm MLC NAND

The SM2246EN SATA (6Gb/s) client SSD controller from Silicon Motion Technology now supports Micron’s 16nm 128 gigabit (Gb) MLC NAND flash used in building SSDs (solid-state disk).

Featuring four channel SATA 6Gb/s client SSD controller, SM2246EN is said to offer better performance than eight Channel controllers.

Silicon Motion Technology says by working with Micron’s 128Gb 16nm MLC NAND, the SM2246EN delivers up to 538MB/s sequential read performance and 450MB/s sequential write, as well as up to 67,000*random read IOPS and 65,000 random write IOPS.

Silicon Motion Technology also claims by working with 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 SM2246EN’s firmware and reference design for Micron’s 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 Micron’s 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."
