We are developing high-speed microscopy image processing methods leveraging SSDs. One of them is a method able to extract neural voltage from microscopy video in real time, and we presented it at the International Conference on Bioinformatics and Biomedicine (BIBM) 2023.

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.

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).

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.

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.
