Abstract: According to one embodiment, a memory system is connectable to a host. The memory system includes a nonvolatile first memory, a volatile second memory and a controller. The nonvolatile first memory stores translation information. The translation information associates a logical address and a physical address. The volatile second memory stores location information. The location information associates a logical address and a location where the translation information is stored in the first memory. The controller saves a first memory image in the first memory at a first timing, and saves a second memory image in the first memory at a second timing different from the first timing. The first memory image is a part of a memory image of the location information. The second memory image is another part, different form the first memory image, of the memory image of the location information.

Abstract: A memory system includes a non-volatile memory and a controller circuit. The controller circuit is configured to carry out an atomic write operation in the non-volatile memory in response to an atomic write command, and selectively carry out one of a first operation and a second operation corresponding to address mapping between a logical address and a physical address of the non-volatile memory, along with the atomic write operation. When the first operation is selected, the controller circuit starts to update the address mapping after receiving a notification that writing of all data of the atomic write operation has been completed. When the second operation is carried out, the controller circuit starts to update the address mapping before receiving the notification.

The second data is corresponding to the first data in the first memory. The second process is copying third data within the first memory. The third data is corresponding to the second data determined to be valid. The third process is updating translation information for the third data. The processor caches, in the first cache area, only a data-unit including translation information for the first process.

Abstract: According to one embodiment, a memory system is connectable to a host. The memory system includes a first memory including a cache area, and a memory controller. The memory controller sets the available amount of the cache area in response to a first command from the host. In a case where the available amount of the cache area is successfully set, the memory controller transmits a setting completion notification to the host. In a case where the available amount of the cache area cannot be set, the memory controller transmits a notification of non-settable to the host.
