Abstract
A sense amplifier circuit includes a sampling capacitor coupled to the input of an inverting amplifier. The output of the inverting amplifier is coupled to a transistor that includes a current terminal. The memory read operation includes two phases. During a first phase, a terminal of the capacitor is coupled to a first cell. During a second phase, the terminal of the capacitor is coupled a second cell.
