Abstract
A communication device of an embodiment includes a normal operation mode and a low-power consumption mode and includes a first memory unit, a second memory unit, and a control unit. The first memory unit includes a work area for execution of firmware configured to perform basic control of the communication device. The second memory unit stores software for communication with an external device. When transition is performed from the normal operation mode to the low-power consumption mode, the control unit stops voltage supply to the first memory unit and performs control to reduce voltage supplied to the second memory unit to lower than a voltage in the normal operation mode.
