Abstract
According to one embodiment, in response to restoration of power to a memory system, a controller in the memory system notifies a host that the memory system is ready. When an input/output command specifying a logical address belonging to a logical address range is received, the controller selects a block corresponding to the logical address range and rebuilds, based on address translation information and an update log which are stored in the selected block, the latest address translation information corresponding to the logical address range. The controller updates the rebuilt latest address translation information, based on a list of logical addresses corresponding to lost write data, stored in the selected block.
