ABSTRACT:
A semiconductor memory employing an address transition detecting function includes an address transition detection circuit which generates a first signal when a transition of an address signal occurs. The memory also includes a clock circuit for generating a second signal in response to the first signal and a pumping circuit for generating a boosted voltage higher than a power supply voltage used in the memory in response to the second signal. The second signal is applied to the pumping circuit when the boosted voltage is below a predetermined value. In this way, a voltage required for a read operation is maintained at an acceptable level and read operation reliability is improved.
