Understanding NAND Flash MLC Technology

NAND flash memory serves as the storage medium within SSDs, and the type of NAND technology utilized greatly influences the performance and durability of the drive. Multi-level cell (MLC) NAND is a common type of flash memory known for its ability to store multiple bits of data per cell, hence the term “multi-level.” This allows MLC SSDs to achieve higher storage densities compared to Single-Level Cell (SLC) NAND while maintaining a relatively lower cost per gigabyte.

MLC NAND works by varying the electrical charge within memory cells to represent different states, each corresponding to a specific binary value. This enables the storage of multiple bits (typically two or three) within a single cell, hence the term “multi-level.” While this increases storage density and reduces cost, it also introduces complexities in managing data reliability and endurance.
