Abstract
According to one embodiment, the semiconductor memory medium includes a first memory cell, a first word line coupled to the first memory cell, and a row decoder coupled to the first word line. A write operation is executed multiple times on the first memory cell within a first period from after an execution of an erase operation to an execution of a next erase operation. The write operation includes at least one of program loops each including a program operation and a verify operation. In the verify operation, the row decoder applies a verify voltage to the first word line. The verify voltage is set in accordance with a number of executed write operations on the first memory cell within the first period.
