spinpacks

Spinpacks are compact assemblies that implement spin-based information storage and manipulation, drawing on principles from spintronics. In its most common usage, a spinpack encodes data in the quantum spin states of electrons rather than relying solely on electric charge. Spinpacks may integrate magnetic heterostructures such as magnetic tunnel junctions or other spintronic elements to create nonvolatile memory, logic, or sensing capabilities. The term is used across research and industry with varying specifics, but the general idea is to package multiple spintronic components into a modular unit that can be integrated into larger systems.

Applications include experimental quantum information processing, nonvolatile memory similar to MRAM, and compact spin-based sensing and processing. Spinpacks promise high data density and low energy operation, with fast switching, but challenges remain in maintaining coherence, improving fabrication yield, and achieving seamless integration with conventional electronics.

Variations exist in materials (ferromagnetic metals, semiconductors, or topological insulators), configurations (single-layer versus multi-layer stacks), and form factors (compact plug-in modules versus embedded chip-scale packs).
