Capacitor based SneakPath compensation circuit for transistor-less ReRAM architectures

Abstract : With the arrival of crosspoint based memories on the consumer market, high-density resistive memories could be introduced as flash memories replacement or as storage class memory. However, transistor-Less Resistive memory architectures using 1Selector-1resistance bitcells suffer from performances loss due to sneaking current through unselected bitcells. Beyond the back end of line selector design, circuit design solutions have to be pushed in order to improve precision during programming steps. In this paper we propose a novel capacitor based 2-steps SneakPath compensation circuit for transistor-less architectures of resistive memories. Compared to standard SneakPath compensation circuits, it ensures up to 20x of area improvement and more than 3x reduction of the variability effects for a 28nm CMOS node.
