Abstract
A semiconductor memory device. One desired word line of a memory unit is turned on according to the row select signal, and a first delay circuit delays the column select signal a first determined time and outputs to a sense amplifier circuit. The sense amplifier circuit senses the desired word line, amplifies and outputs desired data to a latch circuit according to the column select signal. After that, the memory device can start to access the next data. Further, the delayed column select signal is also output to a second delay circuit to delay a second predetermined time as an output enable signal, and the latch circuit outputs the latched data according to the output enable signal.
