technologies for contemporary access to nonvolatile and volatile memory in a memory device

摘要

Technologies for accessing memory devices from a memory module device include receiving a memory read request from a host and reading, in response to the memory read request, a station of active non-volatile memory devices of the memory module device. while simultaneously accessing a memory module device. The volatile memory device shares data lines from a memory module device data bus with a spare nonvolatile memory device associated with the station of active nonvolatile memory devices. During write operations, each of the active nonvolatile memory device stations and the spare nonvolatile memory device associated with the active nonvolatile memory device station are written to facilitate proper usage leveling of the nonvolatile memory devices. spare nonvolatile memory device can replace failed nonvolatile memory devices from active nonvolatile memory devices. In the event of such an event, the volatile memory device is no longer accessed contemporaneously during station read operations of active nonvolatile memory devices.
