ABSTRACT:
A programmable resistor 10 is provided having a resistive element 12. Resistive element 12 includes a substrate 26 formed by a layer of semiconductor of a first conductivity-type. A current path 32 is formed in substrate 26 by a layer of semiconductor of a second conductivity-type. An interface 36 having interfacial traps is formed between current path 32 and substrate 26. A backgate 24 is formed adjacent substrate 26. A first switch 14 selectively couples backgate 24 to a first voltage while a second switch 16 selectively couples backgate 24 to a second voltage.
