Patent ID: 8053251

Claim:
A method comprising the steps of: providing a memory device operable to store and retrieve information; providing a temperature-compensated capacitor device incorporated into the memory device, the temperature-compensated capacitor device including a ferroelectric capacitor comprising a ferroelectric material, a negative-temperature-variable capacitor comprising a negative-temperature-coefficient-of-capacitance material, the negative-temperature-variable capacitor having a capacitance that decreases with increasing temperature over an operating range of from 25° C. to 125° C., the negative-temperature-variable capacitor matched to the ferroelectric capacitor such that a combined capacitance of the temperature-compensated capacitor device remains generally temperature invariant over the operating temperature range of from 25° C. to 125° C., and an electrical series connection between the negative-temperature-variable capacitor and the ferroelectric capacitor.
