Abstract
A detection circuit that can detect a two-terminal memory cell changing state. For example, in response to electrical stimuli, a memory cell will change state, e.g., to a defined higher resistance state or a defined lower resistance state. Other, techniques do not detect this state change until after the stimuli is completed and a subsequent sensing operation (e.g., read pulse) is performed. The detection circuit can detect the state change during application of the electrical stimuli that cause the state change and can do so by comparing the magnitudes or values of two particular current parameters.
