Abstract
According to one embodiment, a memory system determines, for each of groups corresponding to streams, whether or not a length of write data associated with a set of write commands belonging to a same group reaches a minimum write size of a nonvolatile memory. When a length of write data associated with a set of write commands belonging to a first group corresponding to a first stream reaches the minimum write size, the memory system transfers the write data associated with the set of write commands belonging to the first group from a write buffer in a memory of the host to a first buffer in the memory system, and writes the write data transferred to the first buffer to a first write destination block corresponding to the first stream.
