Abstract
A synchronous memory device which comprises global I/O lines for data input and output from and to a memory core and a pipeline latch circuit for latching data from the global I/O lines. The synchronous memory device includes a circuit that precharges the global I/O lines when a read command signal interrupts a write operation signal, and disables the pipeline latch circuit in order to prevent write data on the global I/O lines from being latched in the pipeline latch circuit. Accordingly, the write data is prevented from being transferred to the pipeline latch circuit at an early stage of the read operation.
