ABSTRACT:
There is disclosed a circuit for controlling the output of a sense amplifier of a semiconductor memory in order to prevent the noises which may be induced by an I/O pad to the sense amplifier as well as to minimize the power consumption. The circuit includes a sense amplifier (600) for sensing and amplifying the data retrieved from a selected memory cell, an I/O pad, a data latch circuit (700) connected to the I/O pad, a sense amplifier output detector (670) for detecting the state of data pair outputted from the sense amplifier, a control signal generator (680) for receiving an address transition detection signal and the output of the sense amplifier output detector to generate a given control signal, and transfer transistors (650, 660) connected between the sense amplifier and the data latch circuit for responding to the output of the control signal generator.
