Abstract

Several emerging spintronic devices have recently been proposed, performing computation by (a) generating spin currents based on input magnet states to switch an output magnet state using Spin-Transfer Torque (STT) [1,2], (b) using multiple nanopillars to drive a domain wall (DW) that switches an output nanopillar using STT [7], and (c) using magnetoelectric (ME) switching at the input, combined with DW automotion, to switch an output state [3]. All of these devices have delays of several nanoseconds. The energy for (a) and (b) is in the range of femtoJoules, while the ME mechanism in (c) facilitates greater energy-efficiency, in the aJ range. These numbers fall some distance away from CMOS, where gate delays and switching energies are in the range of picoseconds (ps) and attoJoules (aJ), respectively.
