摘要

低温环境下的高效计算，包括经典冯-诺依曼、量子和神经形态系统，有望改变大数据处理方式。对高密度、高能效存储器的探索仍在继续，而低温存储器的解决方案尚不明确。我们介绍了一种采用先进硅技术的低温无电容随机存取存储器（C2RAM）单元，它通过可扩展性和多态能力提高了存储密度。值得注意的是，C2RAM 的数据保存时间可长达十多年，具有作为人工突触的潜力。这使得 C2RAM 成为低温计算应用和新兴量子技术的理想非易失性存储器。

An Energy Efficient Memory Cell for Quantum and Neuromorphic Computing at Low Temperatures

Efficient computing in cryogenic environments, including classical von Neumann, quantum, and neuromorphic systems, is poised to transform big data processing. The quest for high-density, energy-efficient memories continues, with cryogenic memory solutions still unclear. We present a Cryogenic Capacitorless Random Access Memory (C²RAM) cell using advanced Si technology, which enhances storage density through its scalability and multistate capability. Remarkably, the C²RAM maintains data for over a decade with its extended retention times and offers potential as an artificial synapse. This positions C²RAM as an ideal nonvolatile memory candidate for cryogenic computing applications and emerging quantum technologies.
