  • Patent number: 10663373
    Abstract: A misfire detecting device for an engine is provided, which includes a processor configured to execute a cylinder operation controlling module to switch an engine operation mode from an all-cylinder operation to a reduced-cylinder operation in which operation of one or some of cylinders are suspended, when an execution condition of the reduced-cylinder operation is satisfied, a misfire detecting module to detect a possibility of misfire occurrence based on an angular speed variation of the engine, and a centrifugal damping part configured to reduce vibration caused by the engine. When a possible misfire state is detected by the misfire detecting module during the reduced-cylinder operation, the cylinder operation controlling module executes an operating-cylinder increase control in which the number of operating cylinders is increased. When the possible misfire state is continuously detected after the operating-cylinder increase control, the misfire detecting module detects the engine misfire.

  • Patent number: 10481971
    Abstract: A data holding characteristic of a memory cell is improved in a memory system in which data is encoded and written to a memory cell. A first candidate parity generation unit generates, as a first candidate parity, a parity for detecting an error in an information section in which a predetermined value is assigned in a predetermined variable area. A second candidate parity generation unit generates, as a second candidate parity, a parity for detecting an error in the information section in which a value different from the predetermined value is assigned in the predetermined variable area. A selection unit selects a parity that satisfies a predetermined condition from among the first and second candidate parities as a selection parity. An output unit outputs a codeword constituted by the information section corresponding to the selection parity and the selection parity.

  • Patent number: 10338984
    Abstract: Detecting a defective cell in a memory in consideration of an error property difference depending on the storage state. A determination unit determines whether there is a possibility of defect for each of unit-of-storages on a memory cell formed with a non-volatile memory. The non-volatile memory undergoes either a reset operation that transitions a state from a low resistive state (LRS) to a high resistive state (HRS) or a set operation that transitions the state from the high resistive state to the low resistive state. The determination unit determines a unit-of-storage in which the number of errors in predetermined one of the reset operation and the set operation has exceeded a predetermined standard, as a unit-of-storage suspected of having a defect.
