SM2244
The SM2244 is an extremely high-performance
SATAII SSD Controller, supporting the new
generation high-speed synchronous mode NAND and
delivering the world highest transfer rate among 4-
channel SATA Solid-State Drives. The SSD controller
provides small-form factor to be more adaptive to the
applications for mobile consumer electronics such as
tablet PC, Netbook, mini-SATA (MO-300A), and Half-
slim SSD (MO-297).
In addition to advanced features and customized
supports, the SM2244 offers longer SSD lifetime with
lower write amplification and wear leveling factor
(WLF). To satisfy the requirements for industrial,
military, and consumer storage systems, the SM2244
is the best solution to the compromise between
performance, power consumption, form size, and cost
considerations.
