NVM full form (Non-Volatile Memory) is a form of storage that maintains its data integrity even if the power is off. It is used in a wide variety of devices and software that necessitate both persistent data storage and rapid retrieval. NVM is an important technological advancement that has many advantages over more conventional forms of volatile memory. By 2028, the market for non-volatile memory is going to be worth USD 138.48 billion, an increase of 8.9% from 2021. NVMs outperform even HDDs and optical drives in read/write speeds.
When magnetic tapes and punch cards were used to store data permanently, NVM was born. Later NVMs like magnetic and optical disks were more efficient and compact. Memory technology advanced with semiconductor-based NVM full form technologies in the late 20th century. Solid-state devices use magnetic fields or electric charges to store data.

NVM full form stores data as electric charges or magnetic fields in cells made of different materials. NVM traps or aligns electrons by detecting a binary value (0 or 1). Trapped or aligned electrons can survive power outages. NVM data storage and retrieval involve these steps:
|Using voltage or current to trap or align electrons in NVM cells to store data.
|Can be done in blocks or pages, depending on the technology
|Applying voltage or current to NVM cells to sense trapped or aligned electrons to retrieve data.
|Can be done randomly or sequentially, depending on the technology
|The process of erasing data from NVM by applying a voltage or current to the cells to release or realign trapped electrons.
|Can be done in blocks or pages, depending on the technology
|The smallest unit of data storage in NVM
|Cells can store one or more bits depending on technology. One or more transistors or diodes act as switches or resistors to control electron flow in a cell.
|A collection of cells arranged in rows and columns that form a logical unit of data storage in NVM
|Depending on the technology, an array can store kilobytes to terabytes. Blocks or pages that erase or write make up an array.
