Abstract
A sense amplifier (SA) includes a semiconductor substrate having a source/drain (S/D) diffusion region; a pair of SA sensing devices both disposed in the S/D diffusion region; an SA enabling device disposed in the same S/D diffusion region as where the pair of SA sensing devices are disposed in; and a sense amplifier enabling signal (SAE) line for carrying an SAE signal, for turning on the SA enabling device to discharge one of the pair of SA sensing devices during a data read from the sense amplifier, wherein the SA enabling device is arranged to provide buffer protection for source/drain terminals of the pair of SA sensing devices.
