A Unique March Test Algorithm for the Wide Spread of Realistic Memory Faults in SRAMs

Abstract

Among the different types of algorithms proposed to test static random access memories (SRAMs), march tests have proven to be faster, simpler and regularly structured. A large number of march tests with different fault coverage have been published. Usually different march tests detect only a specific set of memory faults. The always growing memory production technology introduces new classes of fault, making a key hurdle the generation of new march tests. The aim of this paper is to target the whole set of realistic fault model and to provide a unique march test able to reduce the test complexity of 15.4% than state-of-the-art march algorithm
