Abstract
A semiconductor integrated circuit includes a buffer which outputs a memory control signal to a terminal coupled to a memory device, a power supply control circuit which controls a supply of a power supply voltage from a power supply line to the buffer based on a power control signal, a pull-up control circuit configured to control a pull-up of the terminal based on a pull-up control signal, and a control signal generating circuit. The control signal generating circuit generates, during an output period, the power control signal to supply the power supply voltage to the buffer, and the pull-up control signal to stop the pull-up of the terminal, and generates, during an idle period, the power control signal to stop the supply of the power supply voltage to the buffer, and the pull-up control signal to perform the pull-up of the terminal.
