- Abstract
- A new microcode-based BIST (built-in self test) circuitry for embedded memory components is proposed in this paper. The memory BIST implements march algorithms which are slightly modified by adopting degree of freedom concept to detect address decoder open faults on top of conventional stuck faults. Furthermore, it is shown that the BIST-modified march can capture a few neighborhood pattern sensitive faults coupled with the cellular automata address generator and patterns. The proposed microcode-based memory BIST lends itself to performing different combinations of march and retention tests with less microcode storage than the other approaches.
