  • Patent number: 11763910
    Abstract: Memory devices may perform read operations and write operations with different bit error correction rates to satisfy a bit error correction rate. However, improving the bit error correction rate of the memory device using a single type of read command and/or write commands may result in longer read and write commands. Moreover, using longer read and write commands may result in undesirable higher memory power consumption and may reduce memory throughput. Accordingly, memory operations are described that may use combination of commands with increased bit error correction capability and reduced bit error correction capability. For example, the read operations may use multiple (e.g., at least two) sets or groupings of read commands and the write operations may use multiple (e.g., at least two) sets or groupings of write commands.

Each of the DC leakage current detectors is configured to generate a net voltage at an output thereof indicative of whether a leakage current fault is present at a location at which the respective DC leakage current detector is positioned. A logic device in operable communication with the DC leakage current detectors receives output signals from each DC leakage current detector comprising the net voltage output and locates the leakage current fault in the DC power circuit based on the output signals received from the plurality of DC leakage current detectors.

  • Patent number: 9891694
    Abstract: A method includes initiating a transition from an operating mode to a sleep mode at an electronic device that includes a volatile memory and a non-volatile memory. In response to the initiating, data is copied from the volatile memory to the non-volatile memory and a portion of the volatile memory is disabled. Another method includes determining that a low performance mode condition is satisfied at an electronic device that includes a volatile memory that stores a first copy of read-only data and a non-volatile memory that stores a second copy of the read-only data. A memory mapping of the read-only data is updated from the volatile memory to the non-volatile memory. A portion of the volatile memory that stores the first copy is disabled and access of the read-only data is directed to the non-volatile memory instead of the volatile memory.

  • Patent number: 9613970
    Abstract: A semiconductor nonvolatile memory element is used to form a constant current source in a semiconductor integrated circuit device. The semiconductor nonvolatile memory element includes a control gate electrode, a floating gate electrode, source/drain terminals, a thin first gate insulating film, and a second gate insulating film that is thick enough not to be broken down even when a voltage higher than an operating voltage of the semiconductor integrated circuit device is applied thereto, the first and second gate insulating films being formed below the control gate electrode. Thus, provided is a normally on type semiconductor nonvolatile memory element in which a threshold voltage can be regulated through injection of a large amount of charge with respect to the operating voltage from a drain terminal into the floating gate electrode via the second gate insulating film, and injected carriers do not leak in an operating voltage range.
