Abstract
A data input/output circuit for a semiconductor memory device includes a memory cell array, a latch-type sense amplifier for amplifying the cell data transmitted from the memory cell array in a read mode, a switching transistor for controlling a transmission of the cell data, and is connected between the memory cell array and the latch-type sense amplifier; and a write driver for storing an externally inputted cell data into the memory cell array in a write mode. The switching transistor separates the data line loading from the latch-type sense amplifier at a operation point of the latch-type sense amplifier, so that the operation speed of the sense amplifier is enhanced.
