- Samsung wants the number of NAND layers to reach four digits this decade
- Future M.2 SSDs could expand from 8TB to 32TB capacity
- Cell Multi-Bonding Can Replace Traditional Approaches to NAND Density Growth
Samsung has mapped out a NAND strategy that extends toward 1000-layer memory designs as demand for denser storage continues to accelerate across industries.
The roadmap, disclosed during the IEEE/JSAP VLSI Symposium 2026, extends current vertical scaling plans well beyond existing commercial products.
At the center of those ambitions is a future generation of storage capable of taking familiar SSD capabilities into uncharted territory.
The path from today’s drives to tomorrow’s 32TB M.2 SSDs
Samsung expects its NAND technology to reach approximately 420 layers by 2029 before advancing beyond 560 layers during 2030.
Beyond that point, the company intends to explore architectures that carry between 900 and 1,000 layers within future generations of flash memory.
Instead of building one imposing NAND structure, Samsung plans to combine multiple stacks through its Cell Multi-Bonding technology approach.
The method joins separate NAND structures within a package to achieve densities that resemble a single 1,000-layer device.
Samsung specifically discussed pairing two roughly 450-layer structures to get closer to the effective density associated with future four-digit layer counts.
According to the company’s projections, this agreement could increase storage density up to four times that of current generation solutions.
One example described during the presentation involved an 8TB QLC M.2 drive that eventually expanded to 32TB capacities.
That scenario would allow for substantially larger SSDs without increasing physical dimensions, preserving the compact M.2 form factor that many users remember well.
The same scaling approach could eventually help push enterprise drives past 100TB while bringing Petabyte SSD discussions closer to reality.
The engineering issues standing between Samsung and a petabyte SSD
Samsung acknowledged that increasing the number of layers introduces manufacturing complications that become progressively more difficult as structures grow vertically.
One of the main concerns is wafer warping, where taller structures can warp during production and reduce manufacturing consistency or yield.
Another challenge arises from maintaining alignment accuracy across hundreds of stacked layers, requiring extremely precise overlay control throughout manufacturing processes.
Even relatively minor deviations between layers can impact long-term reliability, performance, and manufacturing efficiency across all finished storage products.
To limit the effects of warping, Samsung plans to introduce a top chuck design aimed at stabilizing increasingly complex wafer structures.
The company also discussed overlap correction technologies aimed at improving alignment accuracy as future NAND structures continue to grow.
These advances come as shrinking conventional processes becomes increasingly difficult, forcing memory manufacturers to adopt more elaborate vertical architectures.
Samsung has separately discussed a record-breaking 400-layer NAND generation that could help push AI hyperscaler SSD capabilities beyond the 200TB barrier..
The company has also linked 430-layer NAND technology to a future in which 100TB SSDs will become increasingly common in enterprise deployments.
Samsung will work with hafnia ferroelectrics to expand the number of practical layers beyond 1000 layers.
However, whether these designs eventually offer 32TB M.2 drives or petabyte SSDs still depends on manufacturing realities rather than roadmaps.
However, Samsung’s latest roadmap suggests that the race to NAND supremacy depends on accumulating ingenuity rather than reducing dimensions.
