Abstract
A memory device includes a memory cell and a sense amplifier. The sense amplifier has a reference circuit configured to output a reference voltage and a sensing circuit connected to the memory cell. A comparator includes a first input and a second input, with the first input connected to the reference circuit to receive the reference voltage, and the second input connected to the memory cell. A precharger is configured to selectively precharge the sensing circuit to a predetermined precharge voltage.
