Abstract
A memory system includes a nonvolatile memory having a plurality of data blocks each of which is a unit of data erase and has a plurality of pages, each of the pages being a unit of data write, and a controller which checks whether or not the nonvolatile memory has been affected by power interruption at power-on time and, if the nonvolatile memory has been affected by power interruption, writes data to that first page in a first data block which has not been affected by power interruption.
