Read margin analysis in an ReRAM crossbar array

Abstract

This paper analyzes effects of design parameters on the read margin of an ReRAM crossbar array. Because ReRAM's crossbar array suffers from small read margin, design parameters must be optimized for large read margin. In this paper, by simulating ReRAM crossbar arrays with various design parameters, we analyze the relations between the read margin and the design parameters: 1) the line resistor, 2) the sensing resistor, 3) the HRS and LRS resistances, and 4) the selectors. ? 2016 IEEE.
