Abstract
A memory system includes a nonvolatile memory including a plurality of blocks, and a controller. The controller manages a plurality of streams and allocates a first erased block for which a data erase operation has been completed among the plurality of blocks as a general-purpose block. In a case where use of a first stream among the plurality of streams is started, if two or more erased blocks for which the data erase operation has been completed are included in the plurality of blocks, the controller allocates a second erased block as the write destination block corresponding to the first stream, and if two or more erased blocks for which the data erase operation has been completed are not included in the plurality of blocks, sets the first erased block as the write destination block.
