Silicon Motion has introduced SM2258, the first turnkey merchant ASIC/firmware SATA 6Gb/s SSD controller solution supporting the latest 3D TLC NAND. The SM2258 controller employs the company's proprietary NANDXtend technology consisting of LDPC hard and soft decoding as well as RAID protection that together triple the P/E cycles of 3D TLC NAND - extending the SSD lifespan and ensuring data integrity. SM2258 also features Direct-to-TLC and SLC Caching algorithms for optimal sustained performance with TLC NAND.

Features:

• Supports 2D/3D MLC and TLC NAND Flash from all the major NAND Flash vendors
• Sequential read performance of up to 560MB/s and sequential write of up to 520MB/s
• Up to 90,000 random read IOPS and up to 80,000 random write IOPS
• Proprietary NANDXtend error-correcting and data protection technology to triple the P/E cycles for 2D/3D TLC SSD devices
• Advanced Direct-to-TLC and SLC Caching algorithms for sustained read and write performance
• Support for ONFI 3.0, Toggle 2.0 and asynchronous NAND
• The latest security protocols, including AES 256, Trusted Computing Group (TCG) and Opal full-drive encryption compliant
• Support for both commercial (0°C to 70°C) and industrial grade (-40°C to 85°C) requirements

The SM2258 SSD controller solution with 3D TLC NAND support is available today.
