Abstract
A .phi..sub.C generation circuit provides a column address buffer control signal to a column address buffer so that the column address buffer maintains a latch operation during the operation period of a differential amplifier. The column address buffer responds to a column address buffer control signal to latch an input address signal for providing a column address signal to a .phi..sub.D and PAE generation circuit. The .phi..sub.D and PAE generation circuit provides a differential amplifier activation signal to the differential amplifier according to a column address signal and a column access activation signal. The differential amplifier responds to a differential amplifier activation signal for amplifying data applied from a data input and output line to provide the same to a selector via a readout data line.
