  • Publication number: 20240078066
    Abstract: An information processing system includes one or more image capturing devices and circuitry. The one or more image capturing devices capture a first slip and a second slip to generate one or more images. The first slip has a first image code corresponding to a first type of identification information thereon, and the second slip has a second image code corresponding to a second type of identification information thereon. The circuitry is to manage a position of the first slip based on the first image code recognized from the one or more images, manage a position of the second slip based on the second image code recognized from the one or more images, and display the position of the second slip in response to an operation performed by a user.

  • Publication number: 20230176750
    Abstract: A semiconductor memory device according to the present invention has a memory cell array, a write-driving/bias-reading circuit, a control circuit and a sense amplifier. The control circuit outputs a VSLC (Verify Sense Load Control) signal generated according to writing data. After the write-driving/bias-reading circuit applied the writing pulse and the complementary writing pulse, the sense amplifier receives the VSLC signal and detects the current difference between two currents respectively flowing through a first data line and a second data line; the first data line and the second data line respectively connecting a true memory cell and a complementary memory cell of the selected pair of memory cell. The control circuit controls to provide the additional current to at least one of the first data line and the second data line so as to make the detected current difference meet the required margin.

  • Patent number: 9269456
    Abstract: A first erase test is performed by applying an erase pulse to series of memory cells which are included in a memory cell array and which are divided into a plurality of groups until the appearance of a group for which the determination that erase is completed is made. A second erase test is performed on other series of memory cells including the series of memory cells on the basis of the number of erase pulses at the time of detecting a group for which the determination that erase is completed is made first.

  • Patent number: 7372743
    Abstract: A control method for a nonvolatile storage device having a storage mode in which in a memory cell provided with a trapping dielectric layer 1-bit data is stored depending on the presence or absence of charge in a first trapping region. In a dynamic reference cell initialization operation, a charge accumulation operation is performed, as a preset operation in the initialization operation, on second trapping regions of first and second dynamic reference cells to a charge accumulation operation on a second trapping region of the memory cell. In addition, at the time of data rewrite, preprogram verification and preprogramming are performed on the first trapping regions. This makes it possible to shorten the time taken for initialization and data rewrite.

  • Patent number: 6839282
    Abstract: A semiconductor nonvolatile memory in which read operations are carried out during write operations, includes: a core having a plurality of cell transistors for storing data; and a write verify circuit for detecting change in a core cell transistor's characteristic during a write operation in which the gate voltage/drain current characteristic of the cell transistor is changed to a condition corresponding to stored data by injecting a charge into or extracting a charge from the core cell transistor; and further includes a write verify inhibition signal generation circuit for generating a write verify inhibition signal in order to deactivate the write verify circuit during a read operation to the core cell transistor. The generation of a mistaken verify decision by the write verify circuit, due to a change in the power supply potential accompanying large current during a read operation, is prevented, as is malfunction of the write verify.
