Temperature Gradients as a Data Storage PrincipleIn this work, we analyze the thermodynamic principles underlying modern data storage systems, including Random Access Memory (RAM), hard disk drive (HDD), flash memory, magnetic RAM (MRAM), ferroelectric RAM (FeRAM), and phase-change RAM (PCRAM), as well as other less well-known data storage mechanisms. The analysis is conducted in the context of data storage and processing in relation to Landauer’s principle, with special emphasis on hysteresis. Analogous to how heat engines are characterized by thermodynamic cycles, data storage systems are examined in terms of the hysteresis loop of their fundamental data unit. We explore the role of heat in data storage systems. Afterward, we introduce the concept of temperature gradient memory (TeGraM) along with a detailed layout of a realizable device. Experimental results demonstrating this technology are also presented.doi.org


브라질의 UFABC에서 냈습니다.

RAM, HDD, Flash Memory, MRAM, FeRAM, PCRAM의 메커니즘을 분석하고, 온도 그라디언트를 사용하는 메모리 장치, TeGraM에 대해 제안합니다.

이는 현재 특허 출원이 되어 있는 상태라네요
