General Description

SN11083 is a high-performance integrated circuit to bridge USB and Flash memory. It provides a flexible and cost efficient single chip solution for external storage applications that intend to utilize the convenience of USB. To help the system manufacturers to build high quality, low cost USB storage systems, several special features are implemented. The embedded translation table helps the system makers to design a high performance NAND type flash device but still keeps the cost low. The proprietary randomization algorithm effectively extends the lifetime of the flash memory, ensuring the robustness of the system. The real time ECC correction keeps the data integrity while still maintains the high data transfer rate.
