Abstract
A circuit includes a reference voltage node, first and second data lines, a sense amplifier, first and second switching devices coupled between the first and second data lines and first and second input terminals of the sense amplifier, third and fourth switching devices coupled between the first and second data lined and first and second nodes, fifth and sixth switching devices coupled between the first and second nodes and the reference voltage node, and first and second capacitive devices coupled between the first and second nodes and second and first input terminals. Each of the first through fourth switching devices is switched on and each of the fifth and sixth switching devices is switched off in a first operational mode, and each of the first through fourth switching devices is switched off and each of the fifth and sixth switching devices is switched on in a second operational mode.
