What is UltraQLC™ Technology?
Artificial intelligence is driving an unprecedented surge in data—placing new demands on storage infrastructure. UltraQLC technology is designed to meet those demands by delivering higher capacity, better efficiency, and consistent performance.
Why UltraQLC™ Technology Matters for AI Infrastructure
In the beginning, flash memory evolved in two-dimensions (or lateral scaling). The next evolution of flash memory involved layering memory cells in three-dimensions (or vertical scaling). Increasing the number of layers causes the number of memory cells per unit area (or bit-density) to increase yielding higher capacity. Our 6th generation of BiCS NAND consists of 162 layers. For QLC memory cells, CBA is a game changer providing a leap in performance over prior generations making QLC suitable for commercial and consumer SSDs.
Our latest NAND, Sandisk’s 8th generation BiCS has 218 layers. The most innovative feature of Sandisk’s 8th generation BiCS is using CMOS Directly Bonded to Array (CBA) technology which takes CMOS circuitry wafers and bonds to memory cell wafers yielding vast improvements in performance and power-efficiency.
