An Improved Method for Detecting Functional Faults in Semiconductor Random Access Memories
C. Papachristou, Sahgal · IEEE Transactions on Computers · 1985
This paper presents an efficient test procedure for the detection of simultaneously present functional faults in semi-conductor random access memories (RAM's). The proposed procedure detects modeled types of functional faults using 36N + 24N log2N operations, which is an improvement over existing techniques. The testing process is twofold: first, it detects simple functional faults by a linear address marching. Second, it detects more complex types of functional faults by a nonlinear address sequencing approach. Simulation results to support the testing procedure are also presented.
