Enabling advanced AI processing at the edge to help boost the smart transformation of industries
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 5TB and a high bandwidth of 64GB/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. The company have also developed high-speed transceiver technology enabling bandwidths of 128Gb/s, along with techniques to enhance flash memory performance. These innovations have been effectively applied to both memory controllers and memory modules.
