Abstract
A hybrid memory 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.
Claims1
A memory module comprising:
- a nonvolatile memory component defining a nonvolatile address space, the nonvolatile address space to store data at nonvolatile-memory addresses;
- volatile memory components defining a volatile address space, the volatile address space to cache the data stored in the nonvolatile address space with first address tags corresponding to the nonvolatile-memory addresses of the data;
- and
- an address buffer component to cache second address tags corresponding to the data cached in the nonvolatile address space.
