摘要： A ferroelectric memory device is disclosed and comprises a logic programmable capacitance reference circuit. The circuit is adapted to generate a reference voltage during a sense mode of operation, wherein the reference voltage comprises a value that is a function of one or more memory conditions. The memory device further comprises a bit line pair, wherein a first bit line of the bit line pair has a ferroelectric capacitor coupled thereto for sensing thereof, and a second bit line of the bit line pair is coupled to the reference voltage. A sense circuit is coupled to the bit line pair and is configured to detect a data state associated with the ferroelectric capacitor using a voltage associated with the first bit line and the reference voltage on the second bit line.

摘要： Apparatus for optical communications (10, 110, 210) includes a low-temperature grown photoconductor (12, 140, 220) coupled to at least one resonant tunneling device (14, 120, 130, 230, 240). When exposed to an input light, low-temperature grown photoconductor (10, 110, 210) absorbs photons, which decreases the resistivity, and thus the resistance of the photoconductor. This decrease in resistance causes a decrease in the voltage drop across photoconductor (12, 140, 220), which causes a corresponding increase in the voltage drop across resonant tunneling device (14, 120, 130, 230, 140).
