Kioxia Achieves Successful Prototyping of 5TB Large-Capacity and 64GB/s High-Bandwidth Flash Memory
Kioxia
Corporation, a world leader in memory solutions, has successfully
developed a prototype of a large-capacity, high-bandwidth flash memory module
essential for large-scale artificial intelligence (AI) models. This achievement
was made within the "Post-5G Information and Communication Systems
Infrastructure Enhancement R&D Project (JPNP20017)" commissioned by
the New Energy and Industrial Technology Development Organization (NEDO),
Japan's national research and development agency. This memory module features a
large capacity of five terabytes (TB) and a high bandwidth of 64 gigabytes per
second (GB/s).
To
address the trade-off between capacity and bandwidth that has been a challenge
with DRAM-based conventional memory modules, Kioxia has developed a new module
configuration utilizing daisy-chained connections with beads of flash memories.
We have also developed high-speed transceiver technology enabling bandwidths of
128 gigabits per second (Gbps), along with techniques to enhance flash memory
performance. These innovations have been effectively applied to both memory
controllers and memory modules.
The practical
application of this memory module is expected to accelerate digital
transformation by enabling the adoption of Internet of Things (IoT), Big Data
analysis, and advanced AI processing in post-5G/6G Mobile Edge Computing (MEC)
servers and other applications.
