SM2256 SSD controller supports Micron’s 16nm TLC NAND, offers the performance and cost-optimized four channel SATA 6Gb/s client SSD controller in the market. Using Micron’s 128Gb 16nm TLC NAND, the SM2256 delivers up to 540MB/s sequential read performance and 460MB/s sequential write, as well as up to 90,000 random read IO/s and 80,000 random write IO/s. Leveraging company’s NANDXtend error-correcting code (ECC) technology, the SM2256 enhances the endurance and retention of TLC NAND, delivering more than three times better reliability for TLC SSD as compared to the existing BCH ECC schemes.

Solid state controller technology is critical to any storage solution,” said Eric Endebrock, VP, marketing, storage business, Micron. “Micron values Silicon Motion’s leadership and collaboration in helping drive the revolution of flash storage to an ever-broadening set of applications.

Our SM2256 solution coupled with Micron’s 16nm TLC NAND delivers the most advanced, cost-effective and reliable SSDs in the market.” said Nelson Duann, VP, product marketing, Silicon Motion. “Our customers can offer a new class of no-compromise, cost-effective SSDs that leverage the strengths of NAND technology advancements at affordable prices.”

Features SM2256 with Micron 128Gb 16nm TLC NAND solution include:

  • Proprietary NANDXtend error-correcting and data protection with LDPC and page RAID technologies

  • Supports ONFI 3.x, Toggle 2.0 and asynchronous NAND
