Abstract
A semiconductor memory device including: a plurality of read sense amplifiers for amplifying an output data of a memory cell; a plurality of read delay controllers for delaying an output data of the read sense amplifier by a predetermined time; a plurality of read latches for outputting an output data of the read delay controller as an external data in response to a read strobe signal; a plurality of write sense amplifiers for sensing and amplifying the external data in response to a write strobe signal; a plurality of write delay controllers for delaying an output data of the write sense amplifier by a predetermined time; a plurality of write drivers for inputting an output data of the write delay controller to the memory cell in response to a write enable signal; and a plurality of data buses for transferring the data.
