Abstract

Random access memory testing by repeated application of march tests was examined. The sequence of addresses formed in each test phase with the constant test structure was used as a variable parameter. The method of the modified address sequences formation is proposed. As a difference measure of the modified address sequences arithmetic distance is used. The efficiency of detection of pattern sensitive faults is estimated depending on modification of the address sequences and their arithmetic distances.
