Abstract: According to one embodiment, when a read request received from a host includes a first identifier indicative of a first region, a memory system obtains a logical address from the received read request, obtains a physical address corresponding to the obtained logical address from a logical-to-physical address translation table which manages mapping between logical addresses and physical addresses of the first region, and reads data from the first region, based on the obtained physical address. When the received read request includes a second identifier indicative of a second region, the memory system obtains physical address information from the read request, and reads data from the second region, based on the obtained physical address information.
