Abstract
According to one embodiment, a memory device includes a nonvolatile memory, a volatile memory, a controller, and a board. The nonvolatile memory stores data. The volatile memory holds a part of the data stored in the nonvolatile memory. The memory controller controls the volatile memory and the nonvolatile memory. The nonvolatile memory, the volatile memory, and the memory controller are provided on the board. The memory controller transmits an interrupt signal to a request source, when the volatile memory does not have any data corresponding to an address which the request source requests to access.
