Intel has this week confirmed it has produced over 10 million solid-state drive storage units based upon the QLC NAND die. Intel’s memory and storage group started producing Intel QLC 3D NAND solid-state drives back in late 2018 and the new milestone establishes the QLC (quadruple-level cell memory) as a mainstream technology for high-capacity drives, says Intel.
“Many have talked about QLC technology, but Intel has shipped it, and at scale,” said Dave Lundell, director of Client SSD Strategic Planning and Product Marketing at Intel. “We have seen strong demand for the cost-effective capacity of our standalone QLC SSD (Intel SSD 660p) and the performance of our Intel Optane Technology + QLC solution (Intel Optane Memory H10).”
If you are the facts about reaching the 10 million milestone :
– Intel QLC 3D NAND is used in the Intel SSD 660p, Intel SSD 665p and Intel Optane Memory H10 storage solutions.
– Intel’s QLC drive has 4 bits per cell and stores data in both 64-layer and 96-layer NAND configurations.
– Intel has been developing this technology over the past decade. In 2016, Intel engineers changed the orientation of the already-proven floating gate (FG) technology to vertical and wrapped it into a gate all-around structure. The resulting 3D tri-cell level (TLC) technology could store 384 Gb/die. In 2018, 3D QLC flash became a reality, featuring 64 layers with four bits per cell, capable of storing a 1,024 Gb/die. In 2019 Intel moved to 96 layers, reducing overall areal density.
– QLC is now part of Intel’s overall storage portfolio, which includes both client and data center products.
