Impact of Current Distribution on RRAM Array with High and Low I-ON/I-OFF Devices

Abstract

Using novel circuit design topology to include the sneak path current as a reference input, the performance of two RRAM devices with I-ON/I-OFF of 26 and 925 were compared for crosspoint array. The RRAM with better current distribution outperforms the RRAM with 36X higher I-ON/I-OFF, on crosspoint array. Thus, the RRAM devices should aim on tightening the current distribution, where high I-ON/I-OFF also consumes high power on circuit.
