Abstract

The present invention relates to a method and apparatus for sensing the resistance state of a programmable resistance memory, using complementary memory elements, one holding the resistance state being sensed and the other holding a complementary resistance state. A sense amplifier detects voltages discharging through the resistance elements to determine the resistance state of an element being read.
