What is an example of nonvolatile memory?

Nonvolatile memory retains its data even when the power is turned off, making it ideal for scenarios where data integrity and persistence are critical. Magnetic core storage exemplifies nonvolatile memory because it uses magnetic materials to store bits of information. This technology, which was widely used before the advent of modern semiconductor memory, allows the information to remain stored regardless of power supply conditions.

In contrast, the other types of memory listed, such as Dynamic RAM, Static RAM, and Cache memory, are all types of volatile memory. These types require a constant power supply to retain the data being processed or stored. Once power is lost, the data within them is erased, demonstrating a fundamental difference between volatile and nonvolatile memory.
