    摘要: A device for connection between supply buses in mixed power integrated circuits includes a diode in series with a transistor with an active p-ring in a semiconductor substrate. The active p-ring surrounds the source and drain of the transistor with a conductive region having the same conductivity type as the semiconductor substrate. A control circuit coupled to the p-ring applies a bias voltage in response to an ESD event affecting the first and second conductors. The bias voltage tends to inject carriers into the semiconductor substrate which enables discharge of the short voltage pulse via a parasitic SCR in the substrate from the anode of the diode to the source of the transistor.

    摘要: A method of programming the memory cell comprises setting the memory cell to an initial state of a first gate threshold voltage, performing a processing sequence including: applying a voltage bias between the gate and the first junction region to cause electric hole to migrate towards and be retained in the trapping layer, and evaluating a read current generated in response to the voltage bias to determine whether a second gate threshold voltage is reached, wherein the second gate threshold voltage is lower than the first gate threshold voltage. The processing sequence is repeated a number of times by varying one or more time the voltage bias between the gate and the first junction region until the second gate threshold voltage is reached and the memory cell is in a program state.

    摘要: To reduce the disturbance between adjacent memory cells, an improved ONO flash memory array is implanted with a pocket on one side of the channel of each memory cell or two pockets of different concentrations on both sides of the channel, thereby resulting in memory cells with asymmetric pockets. Consequently, no disturbances occurred between adjacent memory cells when the ONO flash memory array is programmed or erased by band-to-band techniques, and the disturbances between adjacent memory cells are also suppressed during reading process.

    摘要: A method of a read scheme for a non-volatile memory cell. The non-volatile memory cell includes a substrate, a source, a drain and a gate above a channel separated by a nonconducting charge trapping material sandwiched between first and second insulating layers. The method applies a first positive drain-to-source bias, a second positive source-to-substrate bias, and a third positive gate-to-source bias to read the source-side charges trapped in the trapping material near the source side.
