Abstract
An array of memory cells can be configured into one or more scan chains that uses non-overlapping scan word line pulses in a direction opposite to a direction of the scan chain to shift scan bits in the direction of the scan chain from a scan chain input to a scan chain output. A memory cell may include a latch and a scan input multiplexer. The array includes a pulse generator to derive a pulse generator output from a clock pulse, and a digital delay line to generate the non-overlapping scan word line pulses from the pulse generator output. The scan chain may include a latch from an input buffer and may scan multiple columns or rows.
