STORAGE DEVICE AND POWER SUPPLY CONTROL METHOD THEREFOR, AND ELECTRONIC DEVICE

Provided in the present application are a storage device and a power supply control method therefor, and an electronic device, relating to the technical field of electronics, and being used for solving the problem in the prior art of read disturb caused by an excessive voltage difference between two voltages in a dual voltage domain in a memory. The storage device comprises a voltage detection circuit, a power source switching circuit, a logical unit circuit and a storage unit circuit. The logical unit circuit is powered by a first power source, and a storage unit circuit of a memory is powered by a power source voltage obtained by the power source switching circuit, i.e., being powered by a power source with a larger voltage in the first power source and a second power source. Therefore, by means of the storage device, power consumption profits when the voltage of a first power source is relatively low can be satisfied, and the problem of read disturb can also be avoided; and it can also be ensured that the
