Abstract

A semiconductor memory device includes a memory cell array and a differential amplifying and latching circuit for latching and outputting each of signal pairs output from the memory cell array in case of a first latency operation, and for amplifying a voltage difference of each of the signal pairs output from the memory cell array in case of a second latency operation.
