  • Patent number: 5182726
    Abstract: A circuit and method for rapid removal of drain-column programming voltages from drain-column lines of a memory array. The circuit includes a resistor/transistor connected between a supply voltage and a common node, the resistor/transistor being enabled by a program enable signal. During the discharge operation, the source-drain paths of a driver transistors of the array connect column lines to reference potential. The gates of the driver transistors are coupled to the common node. An enabling transistor has a source-drain path connecting reference potential to the common node and has a gate connected to the program enable signal. The circuit includes at least one inverter, an OR circuit, and a bypass transistor. The bypass transistor has a source-drain path connected between the supply voltage and the common node and a gate coupled to the common node through the inverter and the OR circuit.
