What Is NAND Flash Memory Technology

No doubt that 80 percent of individuals reading this blog are interested in the safety and security of files, and also want to know the basics of NAND memory. NAND flash memory is very vital for the storage of filesin recent times. This blog will open you up to the basics or composition of NAND flash memory and explain why NAND memory has become the best viable option for storing data.

NAND flash memory refers to a non-volatile storage technology that uses electric circuits to retain and retrieve information. The core objective of this flash memory is to ensure there is a reduction in the cost per bit and guarantee an increase in the chip capacity. This also enables flash memory to compete with magnetic storage tools like hard disks. NAND flash memory has become a household name when it comes to mass data storage safety and security in the digital market. NAND Flash is capable of storing large files from cameras, computers, servers, and more. The reason why NAND flash can store and maintain data without power is as a result of the effectiveness embedded in the flash memory cell.

NAND Flash Composition

NAND flash memory is the most frequent utilize memory in the mass market today, this is due to its storage level, affordability, and speed access. When we talk of the composition of NAND Flash Memory, we simply referring to what element is NAND flash made of. Here are some of the composition:

  • NAND Flash Chip
  • NAND flash memory utilize Floating gate transistors
  • It Uses Block Memory For data storage

NAND Flash Chip

The NAND flash chip consists of different layout which includes, Die, Plane, Block, and Page. This chip enables the flash memory to organize data storage. Information is stored in bytes for efficiency. Each page consists of 512 to 4,096 bytes. Some cells consist of one bit while others hold more than three bytes depending on the SSD capacity.

NAND Flash Memory Utilize Floating Gate Transistors

NAND flash utilizes floating gate transistors to store data without energy. Most of the electrical circuits rely on power to maximize charges across the board, which conditions electrons to move through the gate. The floating gate consists of five elements, such as Control gate, Floating gate, Insulator, Poly-Silicon and Source, and Drain. This is where the program or erase cycle of a NAND memory takes bearing.

It Uses Block Memory For Data Storage

It should be noted that NAND flash cells can only be deleted at the block level. Each block of NAND flash consists of a different number of pages, which include bytes for data storage. It also, add extra memory to the various page for storing error-free code. For instance, blocks contain 128 pages.


On the final note, the above composition is some of the elements that NAND flash memory is made of. The effectiveness of NAND Flash Memory in modern day’s data and file storage cannot be overemphasized due to the affordable nature, easy maintenance system, reliable data storage level, speed access and the replacement features associated with it.At FLEXXON, we guarantee customer satisfaction with our products, our customer services is second to none.
