Abstract
A state-holding circuit having improved stability at high temperatures includes a bi-stable circuit capable of assuming one of two reversible and stable states. The bi-stable circuit comprises a plurality of logic components (e.g., transistors) arranged into two sides. Because each of the logic components has a leakage current and/or resistance that varies significantly as a function of temperature, one or more stabilization components, such as transistors or other devices, may be connected to a side of the bi-stable circuit to balance the leakage currents and/or resistances of each side. In certain embodiments, the sole function of the stabilization components is to balance the leakage currents and/or resistances of each side.
