What Does Non-Volatile Memory (NVM) Mean?
Non-volatile memory (NVM) is a type of computer memory that has the capability to hold saved data even if the power is turned off. Unlike volatile memory, NVM does not require its memory data to be periodically refreshed. It is commonly used for secondary storage or long-term consistent storage.
Techopedia Explains Non-Volatile Memory (NVM)
Non-volatile data storage can be classified into two types:
Mechanically addressed systems make use of a contact structure to write and read on a selected storage medium. The amount of data stored this way is much larger than what’s possible in electrically addressed systems. A few examples of mechanically addressed systems are optical disks, hard disks, holographic memory and magnetic tapes.
