Abstract:
An integrated circuit chip is provided that comprises on-chip memory and test circuitry. The test circuitry is configured to perform operational testing of the on-chip memory. The test circuitry comprises a controller which is configured to perform a selection out of a plurality of test algorithms to perform the operational testing. The plurality of test algorithms includes a fault detection test algorithm to perform operational testing of the on-chip memory in order to detect whether or not there is a memory fault, without locating the memory fault. The plurality of test algorithms further includes a fault location test algorithm to perform operational testing of the on-chip memory in order to detect and locate a memory fault. Further, a method to perform a memory built-in self test and an MBIST (Memory Built-In Self Test) control circuit template are provided.
