ABSTRACT:
A data output control circuit of a semiconductor memory device. The data output control circuit comprises an input signal detector for detecting a desired signal, a controller for selecting one of a plurality of data output buffers and a data output controller for driving the selected data output buffer. A signal for driving and controlling the data output buffer is enabled after the data of a given memory cell is supplied to an input terminal of the data output buffer so that any unnecessary transition operation of data can be eliminated to reduce the current dissipation of a semiconductor memory chip and to prevent the deterioration of data access time for the purpose of improving the yield of the semiconductor memory chip.
