A programmable memory test interface for testing a memory device is disclosed. The interface includes a plurality of programmable input pins and output pins. The interface also includes a logic interfacing means for connecting external signals to the plurality of programmable input pins and output pins. The external signals are processed by the logic interfacing means and then communicated to a plurality of memory connection pins that couple up to the memory device. The logic component means is capable of being configured in accordance with one or more memory testing methodologies including a serial built-in-self-test (BIST), a parallel built-in-self-test (BIST), a parallel test, a serial test, and a scan test. The configuring is performed by selectively interconnecting selected ones of the plurality of input pins and output pins to the external signals that drive the logic interface means in a test mode that operates in one or more memory testing methodologies or a mission mode.

Programmable universal test interface for testing memories with

Disclosed is a programmable memory test interface. The test interface includes logic circuitry configured to be integrated to a memory device. The memory device has a plurality of receiving connections that are configured to be coupled to a plurality of internal connections that couple to the logic circuitry. The interface further includes a plurality of programmable input pins and output pins leading to and from the logic circuitry, and the programmable input pins and output pins are configured to receive control signals from a test controller for operating the memory device in either a test mode or a mission mode. The programmable input pins and output pins are selectively interconnected to transform the logic circuitry into at least one type of memory testing methodology interface.
