Abstract:
Some embodiments of the present disclosure relate to a sense amplifier architecture that facilitates fast and accurate read operations. The sense amplifier architecture includes a folded cascode amplifier for its first sense amplifier stage, and a pre-charge circuit to establish a pre-charge condition for a senseline and a reference senseline of the sense amplifier. The pre-charge circuit and the folded cascode amplifier each include one or more cascode transistors of the same size and which receive the same bias voltage on a gate thereof. This architecture provides fast and accurate read operations in a relatively small footprint, thereby providing a good blend of cost and performance.
