Memory solutions provider Kioxia Corporation launches and starts shipment of 2Tb (tera bit) Quad-Level-Cell (QLC) memory devices with eight-generation BiCS FLASH 3D flash memory technology. According to Kioxia, the new device has the highest capacity in the industry, which elevates storage devices to a new capacity point that drives growth in multiple application segments including AI.
The latest BiCS FLASH technology helps achieve both vertical and lateral scaling of memory die through proprietary processes and architecture. Additionally, Kioxia has implemented CBA (CMOS directly Bonded to Array) technology, which enables the creation of higher density devices and an industry-leading interface speed of 3.6Gbps. These technologies together can be applied in the creation of 2Tb QLC, resulting in the industry’s highest capacity memory devices.
The 2Tb QLC comes with a bit density approx. 2.3 times higher and a writer power efficiency approx. 70 percent higher than Kioxia’s current fifth-generation QLC device. The latest QLC device has 16-die stacked architecture in a single memory package, which helps it achieve industry-leading 4TB (tera byte) of capacity.
The product is available with a smaller package size of 11.5×13.5mm and a package height of 1.5mm.
Speaking about Kioxia’s latest development, Charles Clancarlo, CEO, Pure Storage, said, “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.
