Abstract
The present invention relates to a nonvolatile semiconductor memory, that is, a flash memory and especially to a NAND type flash memory device capable of selectively controlling data input/output units by an address control. In the NAND type flash memory device, a memory cell array is divided into a plurality of blocks, and a data input/output path is selectively controlled by a predetermined data rate option and introduced addresses to perform data input/output operations at a ×8 or ×16 speed in one chip.
