    Abstract: A charge-transfer transistor couples between a bit line and a sense node for a sense amplifier. During a read operation, a charge-transfer driver drives a gate voltage of the charge-transfer transistor to control whether the charge-transfer transistor conducts during a charge-transfer period. To assist the charge-transfer by the charge-transfer transistor, a first and second cross-coupled transistor are coupled between the bit line and a complement bit line.
