Abstract :
A design-for-testability technique for enhancing the testability of read-write memories is proposed. Parallel testing reduces the test complexity by an order of magnitude. The design does not require additional pins. When the column decoder is inactive in the test mode, control inputs can be activated using the existing pins to exercise various test algorithms. The design is versatile, and several well-known test algorithms can be used
