MONOLITHIC INTEGRATED DRIVER CIRCUITRY SYSTEM FOR THE WORD LINES OF A MATRIX MEMORY

摘要

This invention provides a system for selectively driving one word line of a plurality of word lines in a memory array which includes a first highly capacitive common line connected to a plurality of driver circuits, each of which has connected to its output a respective word line and each of which includes a transistor having a capacitive junction connected to the common line. Means are provided for charging the common line and for rapidly discharging the common line through a selected driver circuit to its associated word line. Additionally, a second highly capacitive common line is connected to a point of reference potential through a resistor, with each of the driver circuits being connected between said first and second common lines.
