Silicon Motion introduces SATAII SSD controller

A high-performance SATAII SSD controller offers extreme stability for data integrity. SM2244LT from Silicon Motion targets embedded systems, industrial SATA DOMs, CFast cards, and low-cost SATA storage for mobile devices. Available in a 9 mm x 9 mm package, the low-power unit supports high-speed synchronous-mode NAND while allowing device makers to use either MLC or TLC NAND flash. It does not require the use of external DRAM.
