Abstract
According to one embodiment, a memory system is provided with a nonvolatile memory, a controller, a volatile memory and an address translation table. The address translation table includes a high level and a plurality of low levels. The high level indicates positions in the nonvolatile memory in which the low levels are recorded. The low levels indicate positions in the nonvolatile memory in which data is recorded. The controller holds the high level of the address translation table in the first area of the volatile memory, and shuts off the supply of power to the second area of the volatile memory based on a transition from a normal-power state to a low-power state.
