Abstract

Some formal models for pattern-sensitive faults (PSF's) in random-access memories are presented. The problem of detecting unrestricted PSF's is that of constructing a checking sequence for the memory. An efficient procedure for constructing such a checking sequence is presented. A local PSF is defined as a PSF where the faulty behavior of a memory cell Cidepends on a fixed group of cell
