  • Quad-Level-Cell (QLC) 3D flash memory sets the industry benchmark for performance, bit density, and power efficiency
  • It is the first QLC 3D flash to reach a 4.8 GB/s interface, ensuring super-fast data transfer between storage and processor
  • This is the breakthrough that could deliver 1 PB (petabyte) storage to data centers

SanDisk has unveiled the chip that could revolutionize data centers and push cloud storage and AI to the next level with its QLC 3D flash memory technology, developed with Kioxia. Employing the companies’ CMOS directly Bonded to Array (CBA) technology, the 10th generation Quad-Level-Cell 3D flash memory has set a new industry standard, representing the baseline for competing memory manufacturers.

The chip has a 60% increase in bit density compared to the 8th generation 3D flash memory, also setting the benchmark for performance and power efficiency.

With a 37 Gb/mm² (gigabits per square millimeter) density, the QLC 3D flash...
