ABSTRACT:
A state control portion causes a sense amplifier portion to be at an active state and for causing the sense amplifier to be at an inactive state. A feedback portion causes the control device to causing the sense amplifier portion to be in the inactive state when a path is formed between a power source and a ground in the sense amplifier. A latch portion holds an output of the sense amplifier output when the path is formed. The state control portion comprises a first transistor acting as a switching device. The feedback portion produces a control signal using an output of the sense amplifier portion and a clock signal obtained from a detection circuit, and supplies the control signal to the first transistor. A second transistor for precharging is connected between the first transistor and the power source.
