We have used Monte Carlo simulation to calculate the shot-noise intensity S I () at ͑two-dimensional͒ hopping using two models: a slanted lattice of localized sites with equal energies and a set of localized sites with random positions and energies. For wide samples we have found a similar dependence of the Fano factor FϵS I (0)/2eI on the sample length L:… (More)

In this paper we analyze the possibility of creating a universal non-volatile memory in a near future. Unlike DRAM and flash memories a new universal memory should not require electric charge storing, but alternative principles of information storage. For the successful application a new universal memory must also exhibit low operating voltages, low power… (More)

With the modern transistor size shrinking below 45 nm the classical drift-diffusion model to describe transport in the conducting channel is loosing its validity. In short-channel devices carriers get accelerated by the driving field and do not thermalize before they reach the drain contact. Thus, the assumption underlying the classical transport model,… (More)

Numerical modeling of correlated single-electron tunneling in uniform two-dimensional arrays of small conducting islands separated by tunnel junctions shows the possibility of soliton-antisoliton avalanches. Though the time duration of any avalanche and the total charge, ⌬Qϭne, transferred across the array during the avalanche are always finite in arrays… (More)

We have used modern supercomputer facilities to carry out extensive Monte Carlo simulations of 2D hopping (at negligible Coulomb interaction) in conductors with a completely random distribution of localized sites in both space and energy, within a broad range of the applied electric field E and temperature T, both within and beyond the variable-range… (More)

— A novel non-volatile logic-in-memory (NV-LIM) architecture is introduced to extend the functionality of the spin-transfer torque magnetoresistive random-access memory (STT-MRAM) to include performing logic operations with no extra hardware added. The access transistors of the one-transistor/one-magnetic tunnel junction (1T/1MTJ) cells are used as… (More)

— Because of the easy integration with CMOS, non-volatility, reconfiguration capability, and fast-switching speed of magnetic tunnel junctions (MTJs), this work proposes and investigates stateful IMP-based logic gates and circuit architecture for future reconfigurable and nonvolatile computing systems. Stateful logic uses the memory unit (MTJ device) as the… (More)

In the present work, the nonlinear equation of motion of Bernoulli-Euler beam is used for investigating the scalability of the shooting method. A parallel implementation of the complete process of computing the nonlinear frequency-response function is presented and its efficiency is studied. The process involves algebraic operations of sparse and dense… (More)
