  • Publication number: 20240071526
    Abstract: A memory apparatus and operating method are provided. The apparatus includes memory cells connected to word lines and disposed in strings and configured to retain a threshold voltage corresponding to data states. A control means is configured to program and verify the memory cells during a program operation. The memory cells associated with predetermined ones of the data states are not verified until the memory cells associated with specific prior ones of the data states finish programming to define verify windows ranging between each one of the specific prior ones of the data states and each one of the predetermined ones. The control means adjusts the verify windows in response to the memory cells associated with one of the specific prior ones of the data states not finishing programming before the one of the predetermined ones of the at least one of the verify windows is verified.

  • Publication number: 20230184862
    Abstract: A static magnetic field generator generates a non-magnetic field region. An AC magnetic field application instrument applies an AC magnetic field to the non-magnetic field region. A detection coil has an axis parallel to a direction of the AC magnetic field in order to detect a magnetization signal. A measuring instrument is connected to the detection coil. A resonance frequency variable device includes a capacitor connected in parallel to the detection coil in order to adjust a resonance frequency of the detection coil and the measuring instrument. A capacity of the capacitor is adjusted such that a resonance frequency of a closed circuit including the detection coil, the measuring instrument, and the resonance frequency variable device including the capacitor coincides with a frequency of a harmonic signal.

  • Patent number: 11639974
    Abstract: A first magnetic field generator generates a magnetic field intersecting a detection object being transported along a transport path. A second magnetic field generator opposite to the first magnetic field generator with respect to the transport path generates a magnetic field intersecting the detection object. A first magnetoresistive element between the first magnetic field generator and the transport path outputs, as a change in resistance, a change in magnetic flux density produced by transport of the detection object. The first and second magnetic field generators are different in a magnetic pole facing the transport path and are arranged with a center of the first magnetic field generator in a transport direction of the detection object and a center of the second magnetic field generator in the transport direction are located at mutually different positions.
