Non-Volatile Memory (NVM) is a type of computer memory that retains data even when the power is turned off. Unlike volatile memory, such as RAM, which loses its information when the device is powered down, NVM ensures that important data remains intact. This makes it ideal for storing files, applications, and system settings. Common examples of Non-Volatile Memory include Flash memory, used in USB drives and solid-state drives (SSDs), and Read-Only Memory (ROM), which is often used to store firmware. NVM is essential for devices that require reliable data storage without the need for constant power supply.
