摘要： An electronic device according to the present technique includes a non-volatile memory in which a program is stored, a volatile memory in which the program read from the non-volatile memory is stored, a controller part for controlling operations of the non-volatile memory and the volatile memory, and a power supply controller for controlling power to the controller part and the volatile memory. The controller part includes a power supply part and a signal fixing part. The power supply part is separated from another power supply line, and power for an interface signal of the volatile memory is supplied from the power supply part thereto. A voltage is supplied from the power supply part to the signal fixing part, and the signal fixing part fixes an output logic of the signal supplied to the volatile memory according to the signal from the power supply controller.
