Abstract
In an embodiment, a memory interface includes integrated circuitry to verify the integrity of the memory interface. The circuitry propagates a test pattern through different paths of the memory interface, and checks the result against a reference value to determine whether the components of the paths are operating within an acceptable tolerance. The memory interface can also communicate with ATE to initiate such tests and return the results to the ATE.
