ABSTRACT:
A circuit and method for limiting voltage swing on the complementary bit lines of a memory device. Complementary bit lines of the memory device are coupled to a sense amplifier through first and second p-channel isolation devices. A low voltage is applied to a gate of the p-channel isolation devices to activate the p-channel isolation devices such that one of the first and second p-channel isolation devices establishes the low logic level on one of the complementary bit lines at a voltage that limits the swing on the complementary bit lines.
