Abstract:
A programmable element, comprising:a first device on a substrate having a first electrode and a first insulator disposed between the substrate and said first electrode, said first insulator having a first value of a given parameter; a second gain device having an FET on a substrate having a second electrode and a second insulator disposed between the substrate and said second electrode; said second insulator having a second value of said given parameter that is different from said first value; wherein said first and second electrodes of said first and second devices are coupled to one another on a continuous layer; and a source of programming energy coupled to said first device and causing it to permanently decrease in resistivity and not effecting the second device or the second insulator, wherein a programmed state of said first device is indicated by a conductive state of said second device.
