A sense amplifier for a memory circuit is presented that can reduce sensing times by introduction of a local reference generator. The sense amplifier includes two capacitors that are pre-charged prior to a sensing operation. A first of the capacitors is connected so that it can discharge through a selected memory cell at a rate dependent on the conductivity of the selected memory cell. After a sensing interval in which the first capacitor can discharge through the selected memory cell, the voltage level on the first capacitor is compared with the voltage level on the second capacitor to determine the result of the sensing operation.
