Abstract
An integrated nonvolatile memory control subsystem and method are disclosed. The integrated nonvolatile memory control subsystem includes a nonvolatile buffer cache, a nonvolatile journal area, nonvolatile storage, and an integrated memory control unit. The integrated memory control unit performs a read operation, a write operation, a commit operation and a checkpoint operation on the cache blocks of the nonvolatile buffer cache and the journal blocks of the nonvolatile journal area. The integrated memory control unit sets each of data blocks of the nonvolatile storage as one among valid state, erasable state and invalid state, depending on being cached or not, being journaled or not, and being a clean cache or not, so as to maintain an authentic original up-to-date consistent data within any one of the nonvolatile buffer cache, the nonvolatile journal area and the nonvolatile storage.
