Abstract
A sense amplifier includes, among other components, a first capacitor adapted to be charged to a precharge voltage, a complementary transistor pair (adapted to connect to the first capacitor, to a reference resistance device, and to a memory cell), a comparator adapted to connect to the complementary transistor pair, and a second capacitor adapted to connect to the comparator. The complementary transistor pair is adapted to produce a first bit voltage based on the precharge voltage and the reference resistance of the reference resistance device. The comparator is adapted to charge the second capacitor to a comparison voltage based on the first bit voltage. The complementary transistor pair is adapted to produce a cell bit voltage based on the precharge voltage and the resistance of the memory cell. The comparator is adapted to compare the cell bit voltage to the comparison voltage to produce an amplified memory cell value.
