This breakthrough positions Samsung at the forefront of NAND innovation as it competes with industry players like SK Hynix, which recently commenced production of 321-layer NAND.
Launch Details and Production Plans
Samsung plans to unveil detailed information about its 400-layer NAND, featuring a 1Tb capacity and triple-level cell (TLC) architecture, during the International Solid-State Circuits Conference (ISSCC) in February 2025. Mass production is expected to begin in the second half of 2025, though some industry analysts suggest that production could start as early as late Q2 if accelerated.
In addition to its 400-layer NAND, Samsung will expand its advanced NAND production lines in 2024. The company plans to add new facilities for its 9th-generation 286-layer NAND at the Pyeongtaek campus, with a production capacity of 30,000 to 40,000 wafers per month. Furthermore, the company will continue converting its Xi’an facility from 128-layer (V6) to 236-layer (V8) NAND manufacturing.
Technological Advancements
The development of 400-layer NAND represents a significant leap in NAND flash memory technology. Evolving from 2D planar designs to 3D NAND, the 400-layer technology leverages vertical stacking of memory cells to achieve higher storage density and efficiency. Samsung’s innovation includes a "triple-stack" architecture, where cells are stacked in three layers, marking a new milestone in high-density memory production.
This technological leap underscores Samsung's commitment to maintaining its leadership in NAND flash memory, catering to the ever-growing demand for high-capacity storage solutions in data centers, mobile devices, and beyond.
