Achieved through Groundbreaking Architectural
Innovations in Scaling and Wafer Bonding Technology
Kioxia Corporation, a world leader in memory solutions, today
announced that it started sample shipments(1) of 2Tb (tera bit)
Quad-Level-Cell (QLC) memory devices with its eighth-generation
BiCS FLASHTM 3D flash memory technology. This 2Tb QLC device has
the highest capacity in the industry(2), elevating storage devices
to a new capacity point that will drive growth in multiple
application segments including AI.
With its latest BiCS FLASHTM technology, Kioxia has achieved
both vertical and lateral scaling of memory die through proprietary
processes and innovative architectures. In addition, the company
has implemented the groundbreaking CBA (CMOS directly Bonded to
Array)(3) technology, which enables the creation of higher density
devices and an industry-leading interface speed of 3.6Gbps(4).
Together, these advanced technologies are applied in the creation
of 2Tb QLC, resulting in the industry’s highest capacity memory
device.
The 2Tb QLC is equipped with a bit density approx. 2.3 times
higher and a write power efficiency approx. 70 percent higher than
Kioxia’s current fifth-generation QLC device which is the highest
capacity in Kioxia’s products. With a 16-die stacked architecture
in a single memory package, the latest QLC device achieves
industry-leading 4TB (tera byte) of capacity. It is available with
a smaller package size of 11.5 x 13.5mm and a package height of
1.5mm.
Charles Giancarlo, Chief Executive Officer, Pure Storage, Inc.,
the IT pioneer that delivers the world’s most advanced data storage
technology and services, highlighted the significance of Kioxia's
latest development for the company's platform: “We have a
long-standing relationship with Kioxia and are delighted to
incorporate their eighth-generation BiCS FLASH™ 2Tb QLC flash
memory products to enhance the performance and efficiency of our
all-flash storage solutions. Pure’s unified all-flash data storage
platform is able to meet the demanding needs of artificial
intelligence as well as the aggressive costs of backup storage.
Backed by Kioxia technology, Pure Storage will continue to offer
unmatched performance, power efficiency, and reliability,
delivering exceptional value to our customers.”
"We are pleased to be shipping samples of our new 2Tb QLC with
the new eighth-generation BiCS FLASH™ technology,” said Hideshi
Miyajima, Chief Technology Officer of Kioxia. “With its
industry-leading high bit density, high speed data transfer, and
superior power efficiency, the 2Tb QLC product will offer new value
for rapidly emerging AI applications and large storage applications
demanding power and space savings.”
In addition to the 2Tb QLC, Kioxia also added a 1Tb QLC memory
devices to its portfolio. In comparison with the capacity-optimized
2Tb QLC, the performance-optimized 1Tb QLC offers approx. a 30
percent faster sequential write performance and approx. a 15
percent improvement in read latency. The 1Tb QLC will be deployed
in high performance applications, including client SSD and
mobile.
Kioxia will continue to develop industry-leading memory products
in anticipation of growing demand for data storage solutions.

the specifications of these samples may differ from those in mass
production. (2) As of July 3, 2024. Kioxia survey. (3) CBA (CMOS
directly Bonded to Array) technology, wherein each CMOS wafer and
cell array wafer are manufactured separately in its optimized
condition and then bonded together. (4) 1Gbps is calculated as
1,000,000,000bits/second. This value is obtained under specific
Kioxia’s test environment, and may vary depending on the user’s
conditions.
* In every mention of a Kioxia product: Product density is
identified based on the density of memory chip(s) within the
Product, not the amount of memory capacity available for data
storage by the end user. Consumer-usable capacity will be less due
to overhead data areas, formatting, bad blocks, and other
constraints, and may also vary based on the host device and
application. For details, please refer to applicable product
specifications. The definition of 1KB = 2^10 bytes = 1,024 bytes.
The definition of 1Gb = 2^30 bits = 1,073,741,824 bits. The
definition of 1GB = 2^30 bytes = 1,073,741,824 bytes. 1Tb = 2^40
bits = 1,099,511,627,776 bits.
* Read and write speeds are the best values obtained in a
specific test environment at Kioxia and Kioxia warrants neither
read nor write speeds in individual devices. Read and write speed
may vary depending on device used and file size read or
