Moments of Entropy Production in Dissipative Devices
Jean-Charles Delvenne, Léopold Van Brandt
We characterize the possible moments of entropy production for general overdamped Markovian systems. We find a general formulation of the problem, and derive a new necessary condit…
Stochastic Nonlinear Dynamical Modelling of SRAM Bitcells in Retention Mode
Léopold Van Brandt, Denis Flandre, Jean-Charles Delvenne
SRAM bitcells in retention mode behave as autonomous stochastic nonlinear dynamical systems. From observation of variability-aware transient noise simulations, we provide an unidim…
Variability-Aware Noise-Induced Dynamic Instability of Ultra-Low-Voltage SRAM Bitcells
Léopold Van Brandt, Jean-Charles Delvenne, Denis Flandre
Stability of ultra-low-voltage SRAM bitcells in retention mode is threatened by two types of uncertainty: process variability and intrinsic noise. While variability dominates the f…
The non-Landauer Bound for the Dissipation of Bit Writing Operation
Léopold Van Brandt, Jean-Charles Delvenne
We propose a novel bound on the mimimum dissipation required in any circumstances to transfer a certain amount of charge through any resistive device. We illustrate it on the task…
