Semiconductor memory device

Abstract

A semiconductor memory device has a memory part, first and second write bit lines coupled to the memory part and used exclusively for writing information into the memory part and first and second read bit lines coupled to the memory part and used exclusively for reading information, held in the memory part, from the memory part. A short-circuiting circuit short-circuits the first and second read bit lines and thereby sets them to the same potential, in a write mode of operation of the semiconductor memory device in which information is written into the memory part via the first and second write bit lines. The short-circuiting circuit permits a read operation to be performed immediately following a write operation, at a high speed.
