Introducing the latest technologies being researched and developed at KIOXIA Corporation and various use cases of flash memories.
-
The erase operation of flash memory is one of the causes of performance degradation in SSDs. We have developed an efficient erase technology for low-latency flash memory-based SSDs and achieved a significant performance improvement in a database application evaluation.
-
In sort benchmark contest founded by Dr. Jim Gray who was a winner of ACM A.M. Turing Award, there is a category called JouleSort to compete energy consumption in data sorting. Our sorting algorithm KioxiaSort was awarded a JouleSort world record on November 27 in 2019.

Usually networked storage is implemented on storage servers with multiple SSDs. However, now it becomes true that storage servers cannot fully utilize the high-speed performance and low latency of NVMe SSDs due to the bottleneck of computing power and limited network bandwidth. To solve this problem, Kioxia is developing SSD that connects directly to the network and enables high-speed, low-latency access (Ethernet SSD).

HMB technology utilizes part of the host memory (DRAM) as if it were its own, and achieves equivalent performance to an SSD with DRAM. As cooperation between the host driver and SSD is necessary, we developed HMB protocols for booting and connection, and have them incorporate PCIe® SSD interface standard, NVMe™ 1.2* with major CPU/OS vendors.
* An interface specification developed for SSDs
NVMe is a trademark of NVMe Express, Inc. PCIe is registered trademark of PCI-SIG.
R&D Organization
Conducts advanced research and development, application system development, and development prototyping in the field of memory including emerging memory
Conducts R&D on BiCS FLASH™, a type of 3D flash memory that KIOXIA was the first to develop in the world, while serving as a bridge between R&D and volume production.
KIOXIA memory and storage solutions enable the success of emerging applications and allow existing technologies to reach their expected potential.
Storage technologies and solutions that support the latest SSDs, such as software-defined solutions that share SSDs across security networks, are introduced.
KIOXIA has established industry-leading R&D frameworks with “memory” technology. We use our various locations to conduct technological innovation while promoting open innovation.
