Abstract
According to one embodiment, when a command for committing data requested to be written is received from a host, a controller calculates a first value in a case where data has not been written up to a final page of a second block that is a multi-value recording block. The first value represents an amount or a data ratio of data written into the second block. The controller writes write data, which is written into a first block that is a binary-value recording block, up to a final page of the second block in a case where the first value is a first threshold or more.
