MEMORY MODULE, MEMORY CONTROLLER, NONVOLATILE STORAGE, NONVOLATILE STORAGE SYSTEM, AND MEMORY READ/WRITE METHOD

摘要

A storage having a nonvolatile RAM of destructive read type. The number of restorations attributed to data read from the nonvolatile RAM is decreased, and the overall life of the storage is prolonged. In a storage having a nonvolatile RAM of destructive read type and a volatile RAM and holding the same data in the nonvolatile and volatile RAMs, data is read out of the volatile RAM and data is written in both volatile and nonvolatile RAMs.
