Abstract:
According to one embodiment, a controller of a host causes a memory device to transit from a first state that is an active state to a second state that is a sleep state in a case where there is no access to the memory device for a first time or more. The controller causes the memory device to transit from the second state to the first state in a case where there is no access to the memory device for a second time or more after the transition to the second state.
