Abstract

This paper deals with test-pattern generation and diagnoses of pattern-sensitive faults in RAM by use of simple pseudorandom M-sequences with an emphasis to built-in structure of these schemes. The problems that may arise during their implementation are discussed and an approach to builtin testing of RAM by such a scheme is given not bothering too much about the silicon area required.
