HYBRID MEMORY MODULE

Abstract:

A hybrid memory module includes cache of relatively fast and durable dynamic, random-access memory (DRAM) in service of a larger amount of relatively slow and wear-sensitive flash memory. An address buffer on the module maintains a static, random-access memory (SRAM) cache of addresses for data cached in DRAM. Together, the DRAM and SRAM caches hasten read and write access and reduce wear for a larger amount of nonvolatile memory.
