Abstract
One aspect in accordance with the present invention provides a memory system receiving a power supply from a host device. The memory system includes a non-volatile semiconductor memory and a controller for controlling writing and reading data to and from the semiconductor memory. The controller operates in such a manner that an amount of each of n currents is deducted from an amount of a current supplied from the power supply, the n currents having n values that gradually increase from the first to n-th.
