Storage device, power supply control method thereof and electronic device

The invention provides a storage device, a power supply control method thereof and an electronic device, relates to the technical field of electronics, and is used for solving the problem of read interference caused by overlarge voltage difference between two voltages in double voltage domains in a memory in the prior art. The memory device includes a voltage detection circuit, a power switching circuit, a logic unit circuit, and a memory unit circuit. Wherein the logic unit circuit is powered by the first power supply, and the storage unit circuit of the memory is powered by the power supply voltage obtained by the power supply switching circuit, namely, the power supply with the larger voltage in the first power supply and the second power supply is used for supplying power. Thus, the storage device can meet the power consumption income when the voltage of the first power supply is low, the problem of read interference can be avoided, and the read-write speed in a high voltage range can be increased, so tha
