Abstract
To include a power-down control circuit that suspends an operation of a predetermined internal circuit in response to a power-down command, and an external terminal to which a selection signal is input from outside simultaneously with issuance of a power-down command. The power-down control circuit suspends an operation of a DLL circuit when the selection signal is at a low level, and continues an operation of the DLL circuit when the selection signal is at a high level. According to the present invention, by using the selection signal input simultaneously with a power-down command, mode selection can be made on-the-fly.
