Logic gates based on the resistive switching random access memory (RRAM) allow normally-off digital computing because of the nonvolatile nature of the RRAM switch [1]. An extremely small area consumption can be achieved because of the 2-terminal structure of the RRAM switch and its capability of 3-D stacking. However, the details of RRAM organization within the array must be thoroughly investigated. This paper discusses the array organization and the select/unselect schemes of the RRAM logic circuits. We demonstrate a 1-bit adder to support the high functionality of RRAM logic. These results support RRAM as a promising technology for nonvolatile logic circuits beyond CMOS.
