Non-volatility

Definition

Non-volatility refers to the ability of a device or material to retain its information even when power is removed. This characteristic is crucial for storage solutions, as it allows data to persist without the need for continuous power supply, making it an important feature in various memory technologies like memristors and resistive switching devices.
