MEMORY CONTROL DEVICE, MEMORY DEVICE, AND MEMORY CONTROL METHOD

摘要

According to one embodiment, a memory control device includes a first controller, a second controller, an access module, and a response sort module. The first controller controls processing of a data access command to a nonvolatile memory from a host. The second controller controls processing assigned to the second controller between the first controller and the second controller. The access module performs data access to the nonvolatile memory in response to a command from the first controller or the second controller. When an error occurs in the data access by the access module, the response sort module returns a response to the second controller instead of the first controller.
