What Is a Memory Resistor?
A memory resistor, or memristor, is a non-volatile memory device that regulates current flow and remembers its resistance state even when powered off. It enables high-speed, energy-efficient, and scalable memory technologies for modern electronics.
Substrates Used to Fabricate Memristors
- Silicon (Si): Widely used for its compatibility with CMOS processes and excellent thermal and electrical properties.
- Silicon Dioxide (SiO₂): Provides insulation and stability as part of the memristive switching layers.
- Titanium Dioxide (TiO₂): Commonly used for its high switching performance due to oxygen vacancy dynamics.
- Flexible Substrates (e.g., Polyimide): Enable bendable and portable devices for wearable electronics.
- Sapphire (Al₂O₃): Offers excellent thermal conductivity and radiation resistance for specialized applications.
- Glass Substrates: Ideal for transparent electronics and displays.
- Transition Metal Dichalcogenides (TMDs): Used in ultrathin, high-performance memory devices.
Applications of Memristors
- Data Storage: High-density, non-volatile memory solutions.
- Neuromorphic Computing: Mimics biological synapses for AI and machine learning systems.
- Edge Computing: Compact and energy-efficient memory for IoT devices.
- Programmable Logic: Reconfigurable circuits for dynamic computing tasks.
