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…
Strong intervalley mixing between copropagating quantum Hall edge channels in a silicon MOSFET
Gento Yamahata, Takase Shimizu
Copropagating quantum Hall edge channels provide a promising platform for compact electron interferometry and flying quantum states. In silicon, the valley degree of freedom offers…
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…
Scalable Parallel Single-Electron Pumps in Silicon with Split-Source Control in the Nanoampere Regime
Gento Yamahata, Takase Shimizu, Katsuhiko Nishiguchi +1
Parallelizing single-electron pumps offers a promising route to achieving nanoampere-level currents crucial for quantum current standard applications. Achieving such current levels…
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…
