Abstract

See full text

A nonvolatile-semiconductor-memory-device including a cell array having a plurality of MATs (unit-cell-array) disposed in a matrix, the MATs each include a plurality of first lines, a plurality of second lines crossing the first lines, and memory cells being connected between the first and second lines. The device further includes a first and second drive circuit selecting the first and second lines connected to the memory cells of each MAT that are accessed, and driving the selected first and second lines to write or read data. The memory cells form a page by being connected to each first line selected from the MATs. The device also includes a data latch latching the write or the read data in units of pages, where the first and second drive circuit drive the first and second lines multiple times to write or read data for one page in and out of the cell array.
