Complementary resistive switches offer a solution for sneak-path issues in memory arrays. Modeling reveals a trade-off between read/write voltages, with cell disturbance limiting writing speed.
Area of Science:
- Materials Science
- Electrical Engineering
- Computer Engineering
Background:
- Passive crossbar memory arrays face challenges with sneak-path currents.
- Complementary resistive switches (CRSs) have been proposed as a solution.
Purpose of the Study:
- To model and analyze the switching dynamics of CRSs.
- To evaluate the read/write schemes of CRS-based memory arrays.
Main Methods:
- Development of a computational model for CRS switching dynamics.
- Validation of the model using experimental data.
- Analysis of read/write voltage windows and cell disturbance.
Main Results:
- The model accurately captures CRS switching behavior.
- A critical trade-off exists between read and write voltage windows.
- Preventing disturbance on unselected cells is crucial for functionality.
Conclusions:
- CRS technology shows promise for mitigating sneak-path problems.
- Design constraints impact writing speed and operational parameters.
- Further optimization is needed for practical memory array applications.

Schottky Barriers
Schottky barriers arise when a metal with a work function (Φm) contacts a semiconductor with a different work function (Φs). Initially, electrons transfer until the Fermi levels of the metal and semiconductor align at equilibrium. For instance, if Φm > Φs, the semiconductor Fermi level is higher than the metal's before contact. The semiconductor's...
