  • Patent number: 9892763
    Abstract: Disclosed are methods, circuits, apparatuses and systems for providing power to a dynamic load such as a non-volatile memory array. According to embodiments, a voltage source may be adapted to generate and output a supply current at substantially a target voltage through a regulating transistor whose channel is in series between an output terminal of said charge pump and an input terminal of said NVM array. A discharge circuit branch coupled to an output terminal of the regulating transistor may be adapted to drain away current from the regulating transistor output terminal when a voltage at the regulating transistor output terminal exceeds a first defined threshold voltage. A bulk regulating circuit branch coupled to a bulk of the regulating transistor may be adapted to reduce a bulk-voltage of the regulating transistor when a voltage at the regulating transistor output terminal exceeds a defined threshold voltage.

  • Patent number: 8995201
    Abstract: Disclose is a non-volatile memory (NVM) cell sensing circuit. The sensing circuit may include a sense-side-line conditioning circuit segment adapted to condition a sense-side-line of the NVM cell. Conditioning may include adjusting a charge density within the NVM cell sense-side-line during a first NVM cell current sensing phase. The conditioning circuit segment may also be adapted to maintain an NVM cell current sensing condition during a second NVM cell current sensing phase. Adjusting a charge density within the NVM cell sense-side-line may include inducing current in the sense-side-line in a direction opposite to the sensing current.

  • Patent number: 8760930
    Abstract: A source-sensing configuration for non-volatile memory devices to simultaneously read 2 bits in two different memory cells sharing a same word line is disclosed. In a first cell arrangement, a drain of a first read cell is biased and its source and that of two adjacent cells in a direction towards the second read cell are connected through source bit lines to a source sense amplifier. In a second cell arrangement, the drain of the second read cell is biased and its source and that of its two adjacent cells in a direction towards the first read cell are connected through source bit lines to a source sense amplifier. A memory cell acts as a cell pipe and joins together the first and second cell arrangements. Driving all six source bit lines simultaneously allows the 2 bits to be simultaneously read while maintaining currents due to pipe effect substantially minimized.

  • Patent number: 8253452
    Abstract: The present invention is a circuit and method for providing a reference voltage and/or one or more circuit/circuit-block enabling signals for an IC. As the voltage level on a power supply line ramps upward towards or above a nominal operating voltage, a first threshold voltage detector circuit segment may be activated and may begin to generate a bandgap reset signal once the voltage level of the power supply reaches a first threshold voltage level. The bandgap reset signal may trigger the power-up and operation of a bandgap reference circuit segment, and according to further embodiments of the present invention, a second threshold voltage detector circuit segment, which second threshold voltage detector circuit segment may be matched with the first voltage detector circuit, may generate a voltage reset signal indicating that the bandgap reference source is powering-up. Once the supply voltage reaches a third threshold reference voltage, the first detector may disable the bandgap reset.
