  • Patent number: 10783034
    Abstract: According to one embodiment, in a memory system, a controller is configured to write a first data among write data to be written across the multiple chips of the first memory area into part of the first memory area and write, in response to a power supply disconnection being detected before writing a second data among the write data into the first memory area, a first information about a storage location where the second data has been stored and the second data into the second memory area. The controller is configured to read, in response to power return being detected, the first data from the part of the first memory area, and read the first information from the second memory area. The controller is configured to generate a second information about a reference location to access the second data based on the read first information.

  • Patent number: 10649891
    Abstract: A storage device includes a nonvolatile memory, and a controller configured to perform, in response to commands from the host device, a read operation and a write operation on the nonvolatile memory. The controller divides a logical address space of the storage device into a plurality of subspaces and manages a priority value for each of the subspaces, the priority values of the subspaces determining an order for setting up the subspaces upon start-up of the storage device.

  • Publication number: 20180328239
    Abstract: A communicating hole, which communicates between a clearance space and the outside of a cover member, is formed in the cover member, and a seal cap is fitted to and retained in a distal-end opening of the communicating hole. The seal cap includes a cap main body having a ventilation through hole formed in an internal axial direction and an outer peripheral wall configured to engage with the communicating hole, a supporting portion fitted, from the outside, into a recessed groove formed in an outside end face of the cap main body, and a ventilation filter located on a bottom face of the recessed groove and retained and sandwiched between the cap main body and the supporting portion. Therefore, an internal pressure rise in the clearance space between the cover member and an electric motor can be effectively suppressed, and thus improved mountability and retainability can be obtained.

  • Patent number: 9940071
    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.

  • Patent number: 9683465
    Abstract: A valve-timing control apparatus varies a relative phase between a cam shaft and a crankshaft by energizing an electric motor through a power-feeding brush provided to be in contact with a slip ring. The valve-timing control apparatus includes a retaining member slidably retaining the power-feeding brush; a connector provided in the retaining member and connected to a power source; a pigtail harness including one end portion connected with the power-feeding brush, and another end portion connected with a terminal of the connector through a fixing portion; and a guide portion provided in the retaining member and including an outer circumferential surface formed in an arc-shape. The pigtail harness bends along the outer circumferential surface of the guide portion. The another end portion extends substantially in a linear arrangement from the fixing portion to a bending portion at which the pigtail harness bends along the outer circumferential surface.

  • Publication number: 20170031601
    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.
