发明名称 COMPILABLE MEMORY STRUCTURE AND TEST METHODOLOGY FOR BOTH ASIC AND FOUNDRY TEST ENVIRONMENTS
摘要 A method of implementing a compilable memory structure configured for supporting multiple test methodologies includes configuring a first plurality of multiplexers for selectively coupling at least one data input path and at least one address path between an external customer connection and a corresponding internal memory connection associated therewith. A second multiplexer is configured for selectively coupling an input of a test latch between a functional memory array connection and a memory logic connection, the memory logic connection coupled to the at least one data input path, with an output of the test latch defining a data out customer connection. Flush logic is configured to direct data from the memory logic connection to the data out customer connection during a test of logic associated with a customer chip, facilitating observation of the memory logic connection at the customer chip.
