Abstract
A memory system includes a memory unit with a plurality of first memory cells connected to a first word line and a memory controller to control the memory unit to write data in page units equal in size to the number of first memory cells. The memory unit is configured to write a plurality of pages of data to the plurality of first memory cells and then read each page of data thus written. The memory controller determines whether or not each page of data, as read from the plurality of first memory cells, satisfies a predetermined condition, and registers a determination result for each page indicating whether the predetermined condition was satisfied.
