Abstract
A control circuit for controlling an operation mode in a pseudo-static RAM. A chip enable control circuit generates a first group of control signals in synchronism with a change in level of a chip enable signal. A second control circuit receives a chip select signal and the first group of control signals, latches a chip select signal on the basis of a signal of the first group of control signals, and generates a second control signal in accordance with the latched signal. A third control circuit controls a write enable signal with an inverted replica of the second control signal and an inverted replica of a predetermined one of the first control signals in the first group of control signals.
