Abstract
According to one embodiment, a memory controller includes a first volatile memory, a second volatile memory, and a controller. The first volatile memory temporarily stores therein data acquired from outside. The controller controls the temporarily stored data to be transferred from the first volatile memory to a non-volatile memory, stores correspondence information of the transferred data to the non-volatile memory in the second volatile memory, and updates correspondence information stored in the non-volatile memory based on the correspondence information stored in the second volatile memory by using the first volatile memory after the data transfer as a work area. The correspondence information represents association between a logical address and a physical address of the data.
