Abstract

A method and apparatus are disclosed for sensing the resistance state of a resistance-based memory element using complementary resistance-based elements, one holding the resistance state being sensed and the other holding a complementary resistance state. A sense amplifier detects voltages discharging through the high and low resistance elements to determine the resistance state of an element being read.
