Kioxia Corporation, described in the article as a world leader in memory solutions, announced a successful prototype of a large-capacity, high-bandwidth flash memory module. The module delivers five terabytes of capacity and a sustained bandwidth of 64 gigabytes per second. This development was carried out under the Post-5G Information and Communication Systems Infrastructure Enhancement R&D Project (JPNP20017) commissioned by the New Energy and Industrial Technology Development Organization, referred to as NEDO.
To overcome limits seen with conventional DRAM-based memory modules, Kioxia developed a new module configuration that uses daisy-chained connections with beads of flash memories. The company also developed high-speed transceiver technology capable of 128 gigabits per second and implemented techniques to enhance flash memory performance. According to the article, these technological advances have been applied to both memory controllers and memory modules in the prototype.
The announcement frames the prototype as addressing a long-standing trade-off between capacity and bandwidth in memory design, especially relevant for large-scale Artificial Intelligence models that demand both large capacity and high data throughput. The article does not specify production timelines, costs, target systems, or compatibility details. It limits its claims to the successful prototyping and the technical features listed, including the 5 TB capacity, 64 GB/s bandwidth, daisy-chained flash configuration, the 128 Gbps transceiver capability, and the application of these innovations to controllers and modules.
