Nonvolatile field programmable spin-logic for reconfigurable computing

Abstract

We have fabricated field programmable spin-logic gates based on spin-dependent tunneling (SDT) elements. Here we show their feasibility down to a width of 0.6 μm of the SDT elements that form spin-logic gates. We further demonstrate the clocked operation of a hybrid spin-logic gate consisting of SDT elements and a semiconductor-based sense amplifier. Apart from the nonvolatility of the inputs, the output and the programming information, the experimentally demonstrated concept seems to be suitable for reconfigurable computing operations.
