ABSTRACT:
A semiconductor memory device includes a memory bank which is divided into a plurality of memory blocks including a first memory block and a second memory block. A first sense amplifier control unit activates sense amplifiers connected with the first memory block, in response to a first activation signal. A second sense amplifier control unit activates sense amplifiers connected with the second memory block, in response to a second activation signal. A signal control unit outputs the first activation signal and the second activation signal to the first sense amplifier control unit and the second sense amplifier control unit, separately from each other, the signal control unit outputting the second activation signal to the second sense amplifier control unit by delaying the first activation signal by a predetermined time after the outputting of the first activation signal.
