Kioxia Corporation, AIO Core Co., Ltd. and Kyocera Corporation today announced the development of a prototype of a PCIe® 5.0-compatible broadband SSD with an optical interface (broadband optical SSD). The three companies will develop technologies for broadband optical SSDs to enhance their suitability for advanced applications that require high-speed transfer of large data, such as generative AI, and will also apply them to proof-of-concept (PoC) tests for future social implementation.

Kioxia’s PCIe® 5.0-compatible broadband optical SSD prototype
The new prototype achieved functional operation with the high-speed PCIe 5.0 interface, which is twice the bandwidth of the previous PCIe 4.0 generation[1], through the combination of AIO Core’s IOCore® optical transceiver and Kyocera’s OPTINITY® optoelectronic integration module technologies.
In next-generation green data centers, by replacing the electrical wiring interface with optical and utilizing broadband optical SSD technology significantly increases the physical distance between the compute and storage devices, while maintaining energy efficiency and high signal quality. It also contributes to the flexibility and efficiency of data center system design, where digital diversification and the evolution of generative AI require complex, high-volume, high-speed data processing.
This achievement is the result of the Japanese “Next Generation Green Data Center Technology Development” project JPNP21029. It is subsidized by the New Energy and Industrial Technology Development Organization (NEDO), which is under the “Green Innovation Fund Project: Construction of Next Generation Digital Infrastructure.” In this project, companies will develop next-generation technologies with the goal of achieving more than 40% energy savings compared to current data centers. As part of this project, Kioxia is developing broadband optical SSDs, AIO Core is developing optoelectronic fusion devices and Kyocera is developing optoelectronic device packages.

Kioxia is committed to uplifting the world with “memory” by offering products, services and systems that create choice for customers and memory-based value for society. Kioxia's innovative 3D flash memory technology, BiCS FLASH™, is shaping the future of storage in high-density applications, including advanced smartphones, PCs, automotive systems, data centers and generative AI systems.
About AIO Core Co., Ltd.
AIO Core Co., Ltd. (https://www.aiocore.com/) was established in 2017 as a spin-off from the Photonics Electronics Technology Research Association (PETRA), a technical research association supervised by Japan’s Ministry of Economy, Trade and Industry (METI).
AIO Core is a startup company that develops, manufactures, and markets high-speed optical transceivers under the brand name “IOCore”, utilizing silicon photonics and quantum dot laser technologies.
The “IOCore” modules enable compact, low-power, and high-temperature-tolerant optical signal transmission through optical-electrical conversion, offering high reliability in demanding environments such as medical devices, automotive systems, semiconductor manufacturing equipment, and aerospace applications.
About KYOCERA Corporation
Kyocera Corporation (TOKYO:6971, https://global.kyocera.com/), the parent and global headquarters of the Kyocera Group, was founded in 1959 as a producer of fine ceramics (also known as “advanced ceramics”). By combining these engineered materials with metals and integrating them with other technologies, Kyocera has become a leading supplier of industrial and automotive components, semiconductor packages, electronic devices, smart energy systems, printers, copiers, and mobile phones. During the year ended March 31, 2024, the company’s consolidated sales revenue totaled 2 trillion yen (approx. US$13.3 billion). Kyocera is ranked #874 on Forbes magazine’s 2024 “Global 2000” list of the world’s largest publicly traded companies, and has been named among “The World’s 100 Most Sustainably Managed Companies” by The Wall Street Journal.
