  • Patent number: 11899962
    Abstract: According to one embodiment, an information processing apparatus includes a nonvolatile memory and a CPU. The CPU stores first data in the nonvolatile memory, performs a first transmission of a write request associated with the first data to the memory system, and stores management data including information equivalent to the write request in the nonvolatile memory. In response to receiving a first response to the write request transmitted in the first transmission, the CPU adds, to the management data, information indicating that the first response has been received. The CPU deletes the first data and the management data in response to receiving a second response to the write request transmitted in the first transmission after receiving the first response.

  • Publication number: 20230305754
    Abstract: According to one embodiment, a controller of a memory system reorders a plurality of first write commands in an order in which writing within a first zone is executed sequentially from a next write location within the first zone. The controller transfers a plurality of write data associated with the plurality of first write commands reordered from a write buffer of a host to an internal buffer in a same order as the order of the plurality of first write commands reordered, and writes the plurality of write data transferred to the internal buffer to a first storage region managed as the first zone.

  • Publication number: 20230297246
    Abstract: According to one embodiment, an information processing apparatus includes a nonvolatile memory and a CPU. The CPU stores, to the nonvolatile memory, first data, and management data including information equivalent to a write command associated with the first data and designating a first LBA range, and performs a first transmission of the write command to a memory system. When writing of second data to a second LBA range including a third LBA range that is at least a portion of the first LBA range or deallocation of the second LBA range is requested before a second response to the write command is received, the CPU transmits, to the system, a command to cancel writing to at least the third LBA range from writing of the first data to the first LBA range in accordance with the write command.

  • Patent number: 10875114
    Abstract: In a vapor-phase type heating method, an object is heated by a heated gas containing vapor in a heating furnace. The heat transfer fluid falling from a front surface of the object to a lower portion of the heating furnace is collected, after the vapor comes into contact with the object and cools to liquefy and latent heat of vaporization of the vapor is applied to the object through phase change. The heated gas obtained after heating the object is discharged from an inside of the heating furnace to the circulation route. In the circulation route, the heat transfer fluid is supplied as droplets to the discharged heated gas and is vaporized after heating, and the heated gas including the vapor is supplied to the heating furnace.

  • Patent number: 10754561
    Abstract: According to one embodiment, an information processing apparatus includes a connector to which a storage device is connectable. The apparatus includes a power supply circuit which supplies power to the storage device via one or more power pins of the connector. The first pin of the connector is set to a first electric potential or an open state based on a power supply capability of the power supply circuit. A state of the first pin which is set to the first electric potential indicates that a maximum power supplied from the power supply circuit to the storage device via the one or more power pins of the connector is a first power. A state of the first pin which is set to the open state indicates that the maximum power is a second power.
