  • Publication number: 20240363166
    Abstract: A controller controls a memory including first and second strings. The first and second strings configure first and second string groups, respectively. In each string group, a set of memory cell transistors each from each string configures a unit. The controller is configured to: sequentially write, in the first string group, data in first units to which serially-coupled memory cell transistors respectively belong; sequentially write, in the second string group, data in first units to which serially-coupled memory cell transistors respectively belong; and sequentially write, in the first string group, data in second units to which serially-coupled memory cell transistors respectively belong.

  • Patent number: 12103793
    Abstract: An unloading apparatus comprises a sensor interface, a gripping unit interface and a processor. A sensor interface acquires a photographed image from a sensor that photographs an image of a cargo group. A processor transmits, in a case of successfully recognizing each piece of cargo of a same-type cargo group, a first control signal to the gripping unit to perform unloading according to a first gripping method corresponding to the same-type cargo group, and transmits, in a case of failing to recognize each piece of cargo of the same-type cargo group, a second control signal to the gripping unit to perform unloading according to a second gripping method corresponding to a mixed-type cargo group including different types of cargo.

  • Patent number: 11972802
    Abstract: A communication line is connected to first and second chips, and held at a first signal level. A monitor circuit changes a signal level of the communication line from the first signal to a second signal level while one of the first and second chips uses a current larger than a reference current. When the signal level of the communication line is the second signal level, the other of the first and second chips is controlled to a wait state that does not transfer to an operating state of using a current larger than the reference current.

  • Patent number: 10552047
    Abstract: A memory system includes a memory controller comprising n (where n>2) first data input/output terminals, a first semiconductor chip comprising n second data input/output terminals, each of the second data input/output terminals being connected to a respective one of the first data input/output terminals, and a second semiconductor chip comprising n third data input/output terminals, each of the third data input/output terminals being connected to a respective one of the first data input/output terminals. When a first request signal is output from the memory controller, status data of the first semiconductor chip is output from a first of the second data input/output terminals that is connected to a first of the first data input/output terminals, and status data of the second semiconductor chip is output from a second of the third data input/output terminals that is connected to a second of the first data input/output terminals.

  • Patent number: 10515457
    Abstract: An image collation system comprising: a detection unit that detects an object from an image acquired by imaging a predetermined position using an imaging unit; a tracking unit that tracks an object image of the same object; a selection unit that calculates an evaluated value for each of the object images of the same object and selects the object image of which the evaluated value is equal to or greater than a predetermined value as a best shot image; a collation unit that performs a collation process of collating the best shot image with a registered image and determining whether the object present at the predetermined position is a previously registered object; and a display that displays a performance result of the collation process, the image collation system including a storage unit that stores the best shot image; and a preparation unit that updates or re-prepares an evaluation expression that calculates the evaluated value.
