Kioxia and SanDisk Achieve Breakthrough 3D NAND Technology with Operational QLC Nodes Using Multi Stage Assembly CMOS Bonded Array Architectural Design
Kioxia and SanDisk have accomplished a breakthrough in 3D NAND technology because they achieved their first operational Quad Level Cell nodes through a novel three dimensional memory design. The transition from theoretical density to actual hardware functional capacity has been established through this technological development. The companies reached their achievement through implementation of their proprietary Multi Stage Assembly CMOS Bonded Array architectural design according to their technical joint announcement. The direct copper to copper wafer bonding method enables engineers to create multiple memory layers which function as one unit through their bonding process.
The MSA CBA process successfully implements all of its required functions which enables 3D NAND systems to develop without facing any engineering obstacles. The manufacturing process at previous production cycles encountered two major challenges which included cell current degradation and wafer warping when they attempted to increase the number of layer additions. The new bonding technique establishes electrical current stability across the entire stack while it simultaneously decreases physical deformations that occur during production. Technical data shows this architecture enables semiconductor companies to develop chips which exceed 1000 layers instead of the previously established theoretical maximum.
The companies will present their complete findings at the VLSI Symposium which will take place in the near future. The event will enable global engineers to study MSA CBA architecture data protection methods which operate during testing at high density conditions. Kioxia and SanDisk removed size restrictions from individual memory blocks which allows storage drives to store much larger data volumes while their physical size remains unchanged. The new storage technology will affect all aspects of data storage because it delivers almost double the storage capacity of current premium lithium ion storage products.
The industry has shifted from developing new assembly methods to producing 1000 layer memory through complete assembly methods. The industry waits for the VLSI Symposium to begin while testing the copper bonded arrays for their production capabilities. The assembly method will become the standard for future high density non volatile memory production if it remains economically viable.
