Abstract
According to one embodiment, a controller of a memory system reorders a plurality of first write commands in an order in which writing within a first zone is executed sequentially from a next write location within the first zone. The controller transfers a plurality of write data associated with the plurality of first write commands reordered from a write buffer of a host to an internal buffer in a same order as the order of the plurality of first write commands reordered, and writes the plurality of write data transferred to the internal buffer to a first storage region managed as the first zone.
