    摘要: A semiconductor memory device having flash write mode and initialized mode functions includes a flash write signal generation circuit for generating flash write signals FW and /FW, and a plurality of switching circuits 30 each provided corresponding to one row in a memory cell arrays MA. The switching circuit 30 applies fixed data "0" or "1" to a memory cell connected to one row selected by a row decoder 10, in response to the flash write signal FW or /FW. Because it is not necessary to activate a column decoder when the flash write or the initialized mode operation is conducted, writing speed can be increased while power consumption can be reduced.

    摘要: A data writing method in a DRAM comprises the steps of bringing a row address strobe input signal into an enabling state and successively changing a signal indicative of a row address while the row address strobe input signal is in the enabling state, thereby to write data successively into a plurality of memory cells designated by the row addresses.
