IPC: G11C11/408
Filed: 2001-08-29
Abstract: PURPOSE: A semiconductor memory device is provided to output read data faster by incorporating therein an SRAM interface. CONSTITUTION: A semiconductor memory device having a self-refresh function includes a detection circuit for detecting a change of an output enable signal and generating a state transition detection signal and a decision circuit for comparing the state transition detection signal and a refresh request signal internally generated and generating a signal that indicates a corresponding circuit operation. The chip enable signal /CE falls, and the state transition detection signal acdpz is generated in synchronism with the falling edge of the chip enable signal /CE. In the next read operation, the state transition detection signal acdpz is generated in synchronism with the rising edge of the output enable signal /OE. The chip enable signal /CE is maintained at the low level. That is, there is no need to raise the chip enable signal /CE once as in the prior art. Thus, the semiconductor memory device does not have time T1 necessary for raising the chip enable signal /CE once. As a result, the time necessary for outputting read data is reduced as is clearly seen from the output timings of read data DQ by the second read operations.
