Defect Analysis and Parallel March Test Algorithm for 3D Hybrid CMOS-Memristor Memory

As an attractive option of future non-volatile memories (NVM), resistive random access memory (RRAM) has attracted more attentions. CMOS Molecular (CMOL) architecture, which can alleviate the sneak path problem of one memristor (1R) crossbars and limit its power consumption in 1R crossbars, is used as a large-scale memory system. In this paper, we analyze the electrical defects in a CMOL circuit including open and bridge. A parallel March-like test algorithm is presented for the CMOL architecture, which covers defined faults caused by electrical defects. The test time of the proposed test algorithm is reduced significantly compared with previous test algorithms that are enhanced for CMOL architecture.
