Abstract

See full text

A memory device includes a nonvolatile memory unit and a memory controller. The memory controller is configured to generate a plurality of commands in accordance with requests received from a host and store the commands in a buffer, set a priority level to each of the commands based on contents thereof, and transfer the commands having a first priority level from the buffer to the nonvolatile memory unit during a first time period, and the commands having a second priority level lower than the first priority level from the buffer to the nonvolatile memory unit during a second time period. The first time period and the second time period are fixed recurring time periods, and the second time period begins after expiration of the first time period.
