A Low Power and High Accuracy Threshold Voltage Detection Circuit for Flash Memory

Abstract

Abstract.A low power threshold voltage detection circuit and its accuracy optimization method for NOR flash memory are proposed in this paper. The whole circuit system is composed of data path, ramp voltage generator, and other auxiliary circuits. This memory system with 256Mb cells is simulated in a 65nm 2P3M NOR flash memory process. The simulation results show that the proposed circuit and optimization method achieve low power consumption with a relatively high accuracy.
