QLC NAND flash has already found many applications due to its higher density and lower price than other NAND types. However, a serious limitation is that QLC has relatively low performance (especially write speed).
A new architecture called X-NAND results in both TLC and QLC NAND with read/write performance comparable to SLC.
Such architecture can produce the high-speed, low-cost solution required by such emerging applications as AI/ML, 5G, real-time analysis, VR/AR, and cybersecurity. X-NAND architecture can be applied to SLC to PLC flash.
Simulation shows that X-NAND in SLC can deliver an astonishing read throughput of 85 GB/s. The architecture enables NAND flash to be readily integrated into ultra-high-bandwidth 3D integrated chips.
