Abstract
A semiconductor device capable of automatically transitioning from a standby mode to a deep power down (DPD) mode is provided. The semiconductor device includes: internal circuits capable of operating in response to an input signal from an input/output circuit; and a controller capable of controlling operations of the internal circuits. The internal circuit supporting the DPD mode includes: a measurement part, measuring a time since a time point of the semiconductor device entering the standby mode; a transition time detection part, detecting a case where a measurement time of the measurement part has reached a certain time; and a DPD signal generation part, generating a power down enable signal for further reducing power consumption in the standby mode when a transition time is detected.
