Abstract

A one-shot system for loading a bitline shift register with a typical test pattern is described. Each bitline latch within the bitline shift register is augmented with a one-shot circuit that may pull-up or pull-down the value stored in the bitline latch. The choice of a particular memory test pattern dictates the control of the one-shot circuit.
