3D NAND

What is 3D NAND?

3D NAND is a type of flash memory technology used in SSDs (Solid State Drives) that allows for higher storage capacity and improved performance compared to traditional 2D NAND.

In 2D NAND, memory cells are arranged in a 2-dimensional array on a single plane. In contrast, 3D NAND stacks memory cells vertically, creating multiple layers of memory cells in a single chip. By stacking memory cells in this way, 3D NAND can achieve higher storage capacity while maintaining a smaller physical footprint. 3D NAND also has better endurance and reliability than 2D NAND, as it is less prone to errors caused by interference between memory cells. Overall, 3D NAND is an important technology that has enabled the development of higher-capacity, faster and more reliable SSDs, making them a popular choice for applications that require high-performance storage. HDDs do not use 3D NAND, as they rely on spinning disks and magnetic read/write heads to store and access data.
