Memristors

Definition

Memristors are passive two-terminal electrical devices that maintain a relationship between the charge and the magnetic flux linkage, essentially functioning as a resistor with memory. They can retain information even when power is turned off, making them essential for non-volatile memory applications and enabling novel computational paradigms. Memristors are pivotal in advancing technology beyond traditional CMOS architectures and are particularly suited for mimicking synaptic behavior in neuromorphic computing systems.
