Abstract: This paper puts forward an self-diagnosis bit-oriented algorithm(MARCH-TB +), according to the testing algorithms,we use a shared built-in-self-test structure(parallel structure) to test and diagnose embedded SRAM(2k×1).The experimental results show that the proposed testing algorithm has high fault coverage, strong diagnostic ability and requires less testing time.

Key words: diagnosis algorithm, built-in-self-test, embedded RAM
