Abstract
A multiplexer circuit of a late-write type semiconductor memory device for selectively outputting data to be bypassed to a data output buffer is constructed with at least one or more data channels. Each data channel includes a first switch for transmitting the data in response to a first state of a bypass control signal, a latch part for latching the data output through a first switch, and a second switch for transmitting the data output from the latch part in response to a second state of the bypass control signal. Thus the circuit prevents data errors and improves time interval of cycles in bypass operation at high speed.
