Samsung has created a working prototype of 900-layer 3D NAND memory by joining two 450-layer stacks using a new technology called Cell Multi Bonding.
This is a major step for the storage industry, as it could lead to SSDs with extremely large capacities, potentially reaching close to 1 petabyte on a single drive. Current high-end SSDs have much smaller capacities.
The technology is mainly for AI servers and data centers
Instead of one giant memory stack, Samsung combines multiple smaller stacks, improving manufacturing and reliability.
