In-Memory AM Demodulation Using an All-Silicon Independent-Dual-Gate Gain-Cell Memory with A Leakage Determined by Single-Electron Counting
Katsuhiko Nishiguchi, Toshiaki Hayashi, Kensaku Chida +3
Ultra-low-leakage memories are attracting increasing attention for in-memory sensing and computing. However, achieving sufficiently long retention in silicon memories for analog si…
Charge discreteness and the energy efficiency of information erasure in dynamic random-access memory cells
Takase Shimizu, Kouki Yamamoto, Kensaku Chida +2
A dynamic random-access memory (DRAM) cell stores information as an integer number of electrons on a capacitor, and whether this discreteness is thermodynamically relevant depends…
Coulomb-mediated single-electron heat transfer statistics across capacitively coupled silicon nanodots
Kensaku Chida, Antoine Andrieux, Katsuhiko Nishiguchi
Heat transfer mediated by the Coulomb interaction reveals unconventional thermodynamic behavior and broadens thermodynamics research into fields such as quantum dynamics and inform…
Thermodynamic Constraints in Dynamic Random-Access Memory Cells: Experimental Verification of Energy Efficiency Limits in Information Erasure
Takase Shimizu, Kensaku Chida, Gento Yamahata +1
We measured the energy efficiency of information erasure using silicon DRAM cells capable of counting charges on capacitors at the single-electron level. Our measurements revealed…
Heat-dissipation decomposition and free-energy generation in a non-equilibrium dot with multi-electron states
Chloe Salhani, Kensaku Chida, Takase Shimizu +2
We experimentally demonstrate the decomposition of heat dissipation during free-energy generation in a nanometer-scale dot transitioning to a non-equilibrium steady state via singl…
Experimental Proof of Universal Conductance Fluctuation in Quasi-1D Epitaxial BiSe Wires
Sadashige Matsuo, Kensaku Chida, Daichi Chiba +8
We report on conductance fluctuation in quasi-one-dimensional wires made of epitaxial BiSe thin film. We found that this type of fluctuation decreases as the wire lengt…
