Granted: 2002-05-11
Abstract: To shorten the cycle time of write in the synchronous semiconductor memory. The write pulse generation circuit 13A has pipeline activated signal PEN, light activated signal WEN and synchronous signal ICLK1D as its input, and constitutes flip flop generating pulses of a fixed interval by NAND gate, delay element DL2, etc. When synchronous signal ICLK1D becomes high, the memory write activated signal will be generated till next synchronous signal after the nonactivated signal of constant memory write has been generated. Once the delay amount of the delay element DL1 and that of delay element DL2 are adjusted, the column selection line is correctly written sense amplifier without change while the write data are being displayed in the write bus vs WBUS 2 T/N, and the write time depends upon the cycle time.
