Memory testing system
Abstract:
Techniques are disclosed relating to memory testing. In one embodiment, an integrated circuit is disclosed that includes a memory and an interface circuit. The interface circuit is configured to receive one or more testing signals from a built in self-test (BIST) unit. The interface circuit is further configured to receive, independently from the one or more testing signals, one or more configuration signals from automated test equipment (ATE). The interface circuit is further configured to issue one or more instruction signals to the memory based on the one or more testing signals and based on the one or more configuration signals. In some embodiments, the interface circuit is configured to enable the BIST unit to detect errors in functions the BIST unit is not designed to test.
