The foundation of NAND cell structure
Our customers order NAND based on features and application requirements — not cell density — so why spend time explaining the differences between TLC and QLC? Because understanding the basics of NAND technology provides valuable insights about:
- Why certain types of NAND perform the way they do
- How structure affects performance and price
When deciding which kind of NAND is best suited to your application, consider the maturity of the technology and future usage models.
- QLC is the newest technology deployment. It offers greater densities in a smaller footprint and is positioned as an attractive solution for read-centric applications.
- TLC is a solution that offers a good cost-versus-performance balance. 3D architectures and error correction techniques have improved cycling and performance to enable TLC in areas where it previously did not fit.
- MLC is in decline for new designs.
- SLC for mission-critical data.
