  • Publication number: 20220093181
    Abstract: A memory system includes a memory and a controller. The memory includes at least a first memory cell and a second memory cell. The controller can determine a first stress type that the first memory cell received or a second stress type that the second memory cell received based on a change amount between a first read threshold voltage to read data from the first memory cell when having received stress, and a second read threshold voltage to read data from the first memory cell when having received no stress.

  • Patent number: 11214080
    Abstract: A medium receiving tray is configured to switch between a first state in which the medium receiving tray is accommodated in a device main body and a second state in which the medium receiving tray most protrudes, and the device main body includes a support member that is configured to be support the medium receiving tray. The device main body includes a rail that supports the first tray constituting the medium receiving tray. The support member is at a position protruding from an end portion of the rail in a protruding direction of the first tray from the device main body. The support member is at the retracted position when the medium receiving tray is in the first state, is at the advanced position when the medium receiving tray is in the second state, and supports the first tray constituting the medium receiving tray from below.

  • Publication number: 20210370689
    Abstract: A transport apparatus includes a mounting section on which a medium is to be mounted, a drive section configured to drive the mounting section in a moving direction and a protection section configured to be switched between a protection state for protecting the drive section and a release state for releasing protection of the drive section. The mounting section has a driven section that engages with the drive section and is driven by the drive section. When the driven section driven by the drive section engages with the drive section, the protection section is in the release state, and when the driven section does not engage with the drive section, the protection section is in the protection state.

  • Patent number: 11158376
    Abstract: According to one embodiment, a memory system includes a memory device and a controller. The controller is configured to instruct to apply, to a first word line, a determination voltage that is based on a first value and a first difference value in a case where it is determined whether or not a first data value has been written in a first memory cell, to instruct to apply, to a second word line, a determination voltage that is based on the first value, the first difference value, and a second difference value in a case where it is determined whether or not the first data value has been written in the second memory cell, and to change the first difference value in a case where a first condition is satisfied.

  • Publication number: 20210130120
    Abstract: A recording device includes a first transportation path along which a medium is transported, a recording unit configured to record on the medium on the first transportation path, a second transportation path branching from the first transportation path, a flap located at the junction and configured to be moved to a first position to open the first transportation path and to a second position to close the first transportation path, and a driving section. After the medium passes the junction, the flap is positioned at the second position to come in contact with the medium traveling upstream along the first transportation path and guide the medium to the second transportation path. The flap is moved to the first position by a driving force of the driving section.

  • Patent number: 8683482
    Abstract: Provided is a control method for a computer system including one or more host computers, one or more storage systems, and a management computer. The storage system includes a plurality of controllers connected to the host computers through a network, and one or more logical volumes for storing data used by the host computers. At least one of the logical volumes is assigned to at least one of the controllers. According to the control method, when performance information of a controller exceeds a predetermined threshold, the logical volume assigned to the controller is assigned to another controller other than the controller. Thus, access loads on a storage system used in a network environment are balanced.
