NAND Flash Memory Controller

This NAND flash memory controller supports SLC/MLC/TLC. Two different types are available: host CPU type and AMBA (AXI/AHB/APB) type. The number of NAND interface channel can be customized according to customer's request; hence it's possible to support wide range of read/write speed. Moreover, a total solution including firmware for such important functions like Bad Block Management, Wear Leveling(Dynamic/Static), Garbage Collection, etc., can also be provided.
