Abstract
A self-testing smart memory (28) is provided in which memory test circuitry (46) within the smart memory (28) writes a pattern to a data RAM (32) and a broadcast RAM (34) and then reads the data RAM (32) and the broadcast RAM (34) to determine if any failures exist within the memory locations. Furthermore, a data path tester (50) determines the functionality of a data path (30) within smart memory (28).
