摘要:A built-in self-test (BIST) architecture having distributed algorithminterpretation is described. The architecture includes three tiers of abstraction: a
centralized BIST controller, a set of sequencers, and a set of memory interfaces. The BISTcontroller stores a set of commands that generically define an algorithm for testingmemory modules without regard to the physical characteristics or timing requirementsof the memory modules. The sequencers interpret the commands in accordance with acommand protocol and generate sequences of memory operations. The memoryinterfaces apply the memory operations to the memory module in accordance withphysical characteristics of the memory module, e.g., by translating address and datasignals based on the row-column arrangement of the memory modules to achieve bitpatterns described by the commands. The command protocol allows powerfulalgorithms to be described in an extremely concise manner that may be applied tomemory modules having diverse characteristics.
