摘要： A programmable element that has a first diode having an electrode and a first insulator disposed between the substrate and said electrode of said first device, said first insulator having a first value of a given characteristic, and an FET having an electrode and a second insulator disposed between the substrate and said electrode of said second device, said second insulator having a second value of said given characteristic that is different from said first value. The electrodes of the diode and the FET are coupled to one another, and a source of programming energy is coupled to the diode to cause it to permanently decrease in resistivity when programmed. The programmed state of the diode is indicated by a current in the FET, which is read by a sense latch. Thus a small resistance change in the diode translates to a large signal gain/change in the latch. This allows the diode to be programmed at lower voltages.

摘要： An antifuse device (120) that includes a bias element (124) and an programmable antifuse element (128) arranged in series with one another so as to form a voltage divider having an output node (F) located between the bias and antifuse elements. When the antifuse device is in its unprogrammed state, each of the bias element and antifuse element is non-conductive. When the antifuse device is in its programmed state, the bias element remains non-conductive, but the antifuse element is conductive. The difference in the resistance of the antifuse element between its unprogrammed state and programmed state causes the difference in voltages seen at the output node to be on the order of hundreds of mili-volts when a voltage of 1 V is applied across the antifuse device. This voltage difference is so high that it can be readily sensed using a simple sensing circuit (228).

摘要： A resettable fuse device is fabricated on one surface of a semiconductor substrate (10) and includes: a gate region (20) having first and second ends; a source node (81) formed in proximity to the first end of the gate region; an extension region (52) formed to connect the source node to the first end of the gate region; and a drain node (80) formed in proximity to the second end of the gate region and separated from the gate region by a distance (D) such that upon application of a predetermined bias voltage to the drain node a connection between the drain node and the second end of the gate region is completed by junction depletion. A gate dielectric (30) and a gate electrode (40) are formed over the gate region. Current flows between the source node and the drain node when the predetermined bias is applied to both the drain node and the gate electrode.
