Abstract
An arrangement and method of performing a memory built-in self test (MBIST) on a memory loops together the registers that store the MBIST results. When an error is detected during the MBIST by an MBIST controller, the MBIST results are shifted serially through the register loop as well as off the chip performing the MBIST. Once all the MBIST results are shifted out for further analysis by a host computer, for example, the MBIST controller is in its original state at the time the error was detected as the MBIST results are back in the registers they occupied prior to the shifting out of the MBIST results off the chip.
