Abstract
A semiconductor memory device according to the present invention has a flash write mode of operation as well as a usual single bit write mode of operation, and a flash write switch circuit is provided between a flash write data bus system and parts of data bit lines for concurrently transferring a flash write data bit to the parts of the bit lines prior to activating sense amplifier circuit coupled to the bit lines, so that flash write data bus system merely needs to swing the parts of the bit lines within a relatively small range, thereby allowing a driver circuit coupled to the flash write data bus system to be decreased in size.
