Semiconductor memory device

摘要

A semiconductor memory device including a read and a write structures are provided. The read structure includes: a core sense amplifier part for amplifying data applied on data buses of a core area; a read multiplexing part for multiplexing the output data of the core sense amplifier part according to data width options and transferring the multiplexed data to a peripheral area through data buses; and a data output part for transferring the data of the data buses to a plurality of data I/O pins. The write structure includes: a data input part for transferring data applied on a plurality of data I/O pins to a core area through data buses; a write multiplexing part for multiplexing the data of the data buses according to data width options; and a core driver part for driving the output data of the write multiplexing part to data buses of the core area.
