ON-DEVICE DATA COMPRESSION FOR NON-VOLATILE MEMORY-BASED MASS STORAGE DEVICES

摘要

A non-volatile memory-based mass storage device that includes a host interface attached to a package, at least one non-volatile memory device within the package, a memory controller connected to the host interface and adapted to access the non-volatile memory device in a random access fashion through a parallel bus, a volatile memory cache within the package, and co-processor means within the package for performing hardware-based compression of cached data before writing the cached data to the non-volatile memory device in random access fashion and performing hardware-based decompression of data read from the non-volatile memory device in random access fashion.
