Abstract
A method for sensing data in a resistive memory device including a sense amplifier with an input coupled to a bitline through a capacitor includes activating a word line to form a current path through a resistive memory cell to the bitline, precharging the bitline to a first precharge voltage and precharging the input of the sense amplifier to a second precharge voltage between the first precharge voltage and the decision threshold of the sense amplifier, disabling, after a first predetermined period of time, precharge of the bit line and precharge of the input of the sense amplifier, and latching data at an output of the sense amplifier after a second predetermined period of time.
