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…
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…
Fluctuation Theorem and Microreversibility in a Quantum Coherent Conductor
Shuji Nakamura, Yoshiaki Yamauchi, Masayuki Hashisaka +8
Mesoscopic systems provide us a unique experimental stage to address non-equilibrium quantum statistical physics. By using a simple tunneling model, we describe the electron exchan…
