What is a non-volatile memory?
Non-volatile memory (NVM) is a type of computer memory that can retain data even when the power supply is disconnected. This is in contrast to volatile memory such as Random Access Memory (RAM), which loses its data once the power supply is turned off. NVMs are used in a variety of electronic devices, including computers, smartphones, gaming consoles, and surveillance systems. They come in many different forms, such as Flash memory, Electrically Erasable Programmable Read-Only Memory (EEPROM), and Read-Only Memory (ROM). One of the primary advantages of NVMs is their ability to store large amounts of data for extended periods without the need for any power source. This is particularly useful in situations where data retention is crucial, such as in critical infrastructure systems and aerospace applications. Flash memory, in particular, is widely used in consumer electronics such as USB drives, Solid State Drives (SSDs), and memory cards. Due to their fast read and write speeds, they ha...
