METHOD AND APPARATUS FOR READ OPERATION AND WRITE OPERATION IN SEMICONDUCTOR MEMORY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus for a read operation and a write operation in a semiconductor memory device having an input/output architecture comprising a separate data input bus and data output bus. SOLUTION: In the method for performing the read and write operations in the semiconductor memory device having the input/output architecture comprising the separate data input bus and data output bus, when a read command is inputted in one cycle, a read operation is performed in synchronization with a clock and a write operation is performed in synchronization with a signal that operates during the read operation.
