Last week, Intel's memory and storage group produced Intel QLC 3D NAND solid-state drive (SSD) number 10 million based upon the QLC NAND die built in
'Many have talked about QLC technology, but Intel has shipped it, and at scale,' said
Here are a few quick facts related to the achievement: 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.
