When a data write sequence is started, initially, write data is latched in a data latch circuit corresponding to one memory mat. Then, a program pulse is applied to the memory mat, and data read from a memory cell, which is a data write target bit in the memory mat, is performed. Thereafter, verify determination of the memory mat is performed. After a verify operation for the memory mat is completed, a program pulse is applied to another memory mat, and a verify operation for another memory mat is performed.
