What is NAND Flash Memory ?

There are two types of flash memory. NOR Type flash memory and NAND Type flash memory. A Flash memory is made up of FGMOS or FGMOSFETs (Floating Gate Metal Oxide Field Effect Transistors). Each FGMOS is an electronic component that can store either 0 or 1. This is why these transistors are called cells.

In NAND flash memory, these cells are arranged in series, that’s why we can access this memory only serially. NAND flash memory is non-volatile in nature. It means that it can permanently store its contents even when it is not connected to any power source.

Uses of NAND Flash Memory
This type of flash memory is also used in computers, SSDs, smartphones, digital television, tablets, USB flash drives, etc. These flash memories don’t require direct current but have semiconductors made up of metal oxide that stores that provide the charge to the flash memory.

Features of NAND Flash memory
Non-Volatile Memory
All forms of NAND flash memory are non-volatile meaning the storage devices with NAND flash memory retain the stored data without using a battery or any other voltage source. Such memories can store data for a long period of time without damaging it.

Reprogrammable
The best thing about the NAND flash memories is that you can program them according to your need. The programmable IC chips may contain any kind of data, from documents to videos, so you may use them whenever you need them.

Faster Write and Erase Time
The time required for writing data is less in NAND flash memory, this is why this memory is used in applications where permanent writing is preferred rather than retrieving the data. It is also a unique feature of NAND flash memory that takes less time to delete its contents. Just give the delete command, and an abundance of data will be removed within seconds.

More Storage
NAND flash memory is so dense that you can even get a 2TB storage device from any local computer shop. Scientists and engineers are working to make flash memories with more storage as the latest applications are becoming bigger in size.

Low Manufacturing Cost
The cost of manufacturing NAND flash memory is amazingly low. More well-known manufacturers are building NAND Memory devices with different sizes, features, and designs to fulfill the user's needs. That's why devices with NAND flash memory have become more popular than physical storage devices.
