Flash memory chip / NAND

Shedding light on a whole new standard of capacity and performance.

Samsung V-NAND technology overcomes the capacity limitations of traditional 2D NAND technology with its revolutionary vertical design.
V-NAND also applies innovative Charge Trap Flash (CTF) technology which prevents data corruption caused by cell-to-cell interference.
The synergy of both structural and material innovations leads to improved speed, power efficiency, and endurance.

Vertical expansion breaks through horizontal limit.
Samsung revolutionized the storage industry by shifting the planar NAND to a vertical structure. Samsung V-NAND technology features a unique design that stacks 48 layers on top of one another instead of trying to decrease the cells? pitch size. Samsung used Channel Hole Technology (CHT) to enable cells to connect vertically with one another through a cylindrical channel that runs through stacked cells.

Material innovation that no one can match.
Samsung has shifted the paradigm of material used for NAND. Samsung applies the innovative CTF technology which uses a non-conductive layer of Silicon Nitride (SiN), temporarily trapping electrical charges to maintain cell integrity.

This non-conductive layer wraps around the control gate of the cell, acting as an insulator that holds charges to prevent data corruption caused by cell-to-cell interference.
