Abstract
A dual threshold voltage sense amplifier that is capable of separating the rise time threshold from the fall time threshold, creating a dual sensing threshold voltage. In one embodiment of the invention, the dual threshold voltage sense amplifier is capable of providing a lower threshold for the rise time and a higher threshold for the fall time, thereby reducing the fall time and improving the read speed in asynchronous static memory without substantially increasing the core cell dimension or the overall design size.
