Abstract
In an output buffer control circuit of a memory, the set/reset state of a flip-flop is controlled by an address transition detection output and a read detection output supplied when completion of data read from a memory cell is detected, and the active/inactive state of an output buffer for outputting the readout data from the memory cell is controlled by an output from the flip-flop. According to this arrangement, when an address input transits and the address transition detection output is enabled, the output buffer is inactivated. When data is read out from the memory cell and the read detection output is enabled after the address input transits, the output buffer can be activated.
