Minimal Test for Coupling Faults in Word-Oriented Memories
Paris, France
March 04-March 08
ISBN: 0-7695-1471-5
Most industrial memories have an external word-width of more than one bit. However, most published memory test algorithms assume 1-bit memories; they will not detect coupling faults between the cells of a word. This paper improves upon the state of the art in testing word-oriented memories by presenting a new method for detecting state coupling faults between cells of the same word, based on the use of m-out-of-n codes. The result is a reduction in test time, which varies between 20 and 38%.
Index Terms:
State coupling faults, word-oriented memories, tests, data backgrounds, m-out-of-n codes.
