    摘要: A system and methodology that can minimize disturbance during an AC operation associated with a memory, such as, program, read and/or erase, is provided. The system pre-charges all or a desired subset of the bit lines in a memory array to a specified voltage, during an AC operation to facilitate reducing AC disturbances between neighboring cells. A pre-charge voltage can be applied to all bit lines in a block in the memory array, or to bit lines associated with a selected memory cell and neighbor memory cells adjacent to the selected memory cell in the block. The system ensures that source and drain voltage levels can be set to desired levels at the same or substantially the same time, while selecting a memory cell. This can facilitate minimizing AC disturbances in the selected memory cell during the AC operation.

    摘要: Flash memory cells are presented which comprise a dielectric material formed above a substrate channel region, a charge trapping material formed over the dielectric material, and a control gate formed over the charge trapping material. The cell may be programmed by directing electrons from the control gate into the charge trapping material to raise the cell threshold voltage. The electrons may be directed from the control gate to the charge trapping material by coupling a substrate to a substrate voltage potential, and coupling the control gate to a gate voltage potential, where the gate voltage potential is lower than the substrate voltage potential. The cell may be erased by directing electrons from the charge trapping material into the control gate to lower a threshold voltage of the flash memory cell, such as by coupling the substrate to a substrate voltage potential, and coupling the control gate to a gate voltage potential, where the gate voltage potential is higher than the substrate voltage potential.

    摘要: Methods of operating dual bit memory devices including programming with a range of values are provided. The present invention employs a range of ramp source program pulses to iteratively perform a program operation that employs hot hole injection. The range is related to channel lengths of individual dual bit memory cells within the memory device. To program a bit of a particular dual bit memory cell, a negative gate program voltage is applied to its gate, a positive drain voltage is applied to its acting drain, and its substrate is connected to ground. Additionally, a ramp source voltage of the range of ramp source program pulses is concurrently applied to an acting source of the dual bit memory cell. A verification operation is then performed and the programming is repeated with a decremented ramp source voltage on verification failure.

    摘要: Methods of operating dual bit flash memory devices and correcting over-erased dual bit flash memory devices are provided. The present invention includes a corrective action that employs a negative gate to correct over-erased memory cells without substantially altering threshold voltage values or charge states for properly erased memory cells. The negative gate stress is performed as a block operation by applying a negative gate voltage to gates and connecting active regions and a substrate to ground.

    摘要: An embodiment of the invention relates to a power converter including a resistor divider with an internal node to sense an input line voltage. The internal node is operable as a multifunctional pin. A controller compares a feedback voltage dependent on a power converter output characteristic to a current-sense signal including an offset dependent on a voltage of the internal node to control entry and exit of the power converter from burst mode operation. The node may be employed to manage power converter operation by sensing or controlling its voltage to signal operation in a standby or burst mode, to sense the input line voltage, to enable an external system to signal shutdown to the power converter, and to enable the power converter to signal a delayed restart condition to the external system.
