CONSTITUTION: Data read, from a memory cell MC of one page in one block BL of a memory cell array, are held in a data-holding circuit 12. The data- holding circuit 12 has a plurality of latch circuits 24; in these plurality of latch circuits 24, addresses are specified for the latch circuits 24 by a column address. Then data for rewriting is supplied to the latch circuits 24, in which an address is specified by a column address, and rewrite of data is conducted by holding data by the latch circuit 24.
