Abstract
A memory system includes a semiconductor memory that includes a cell unit having a plurality of memory cells, and a control circuit for controlling the plurality of memory cells, and a memory controller configured to control the semiconductor memory. The control circuit is configured to execute a data read operation on the cell unit by using one or more read voltages, acquire first data by the data read operation, generate second data with a data size smaller than the first data, based on the first data, and transmit the second data to the memory controller. The memory controller is configured to determine, based on the second data, whether or not to rewrite the page data written in the cell unit.
