Abstract
According to one embodiment, a memory system includes a non-volatile memory, a controller for writing data to the non-volatile memory and reading data from the non-volatile memory, and a power supply circuit. The power supply circuit includes a capacitor. The power supply circuit supplies power to the non-volatile memory and the controller from an external power supply and supplies power to the non-volatile memory and the controller from the capacitor if the external power supply is interrupted. The controller controls the power supply circuit to charge the capacitor when current consumption of the non-volatile memory is less than some first current level.
