Abstract
A negative differential resistance device is disclosed which is particularly suited as a replacement for conventional pull-up and load elements such as NDR diodes, passive resistors, and conventional FETs. The NDR device includes a charge trapping layer formed at or extremely near to an interface between a substrate (which can be silicon or SOI) and a gate insulation layer. The NDR device can be shut off during static operations to further reduce power dissipation.
