Original Abstract Submitted
A controller manages a plurality of block groups each including one or more blocks among a plurality of blocks provided in a non-volatile memory. The controller assigns one of the plurality of block groups to each of plurality of zones. The controller writes write data which is to be written to a first zone to a shared write buffer and writes write data which is to be written to a second zone to the shared write buffer. When a total size of the write data in the first zone stored in the shared write buffer reaches a capacity of the first zone, the controller copies the write data in the first zone stored in the shared write buffer to the first block group assigned to the first zone.
