Abstract
A memory system that can effectively use resources includes a nonvolatile memory that includes a plurality of physical blocks and a controller. The controller manages a plurality of superblocks that each include one or more physical blocks among the plurality of physical blocks, and notifies a host of a maximum size among data sizes writable in each of the superblocks, as a first size that is a size of a reclaim unit. Upon receipt of one or more write commands from the host, the one or more write commands designating a first reclaim unit having the first size, the controller writes a first data portion of the first reclaim unit into the first superblock to fill the entire first superblock and then a second data portion of the first reclaim unit into the second superblock.
