Hybrid architecture of microcode memory Built-In Self Test
International Society for Science and Engineering, o.s.
March tests are a popular method to test semiconductor memory for defects, but they’re originally designed to only work on bit-oriented memories. For practical use march tests have been extended for use on word-oriented memories. This extension is done by either using multiple test data vectors and their inversions, or by using serial march test. These tests access each data word in memory as a shift register. This paper is proposing a microcode-controlled built-in self test architecture that allows us to use both access methods during a single test.
