FMS 2023 Tech Focus: The Evolution of Flash Memory in the Era of Big Data

FMS 2023

To keep pace and stay ahead of the continually increasing demands for fast and reliable storage, flash memory solutions must continually evolve. As volumes of big data increase in velocity, flash memory solutions need to evolve to bring a performance driven, cost-effective solution that bridges the gap between TLC NAND and DRAM. 

Enter Compute Express Link™ (CXL) technology, a new interface protocol, when combined with flash delivers a high density, high bandwidth memory solution.  CXL technology was first introduced in 2019 – but this open industry standard, high bandwidth interface found itself center stage at FMS last month. 

At the show, our own Shigeo (Jeff) Ohshima highlighted the fact that CXL technology’s time has come in his keynote address. Pointing to the fact that the amount of data being handled by applications like AI/ML, LLM, IoT, and cloud just continues to grow, Ohshima-san noted that memory expansion will be critical to enabling the efficient processing of all of this data.

Our booth at FMS was the place to be on the show floor. It was where crowds gathered to see our technology innovations and demos including the future roadmap of KIOXIA high bandwidth, low-latency CXL solutions. We showed a working sample of a 1.3 TB CXL 1.1/2.0 x 4 lanes BiCS FLASH™ 3D flash memory-based device in an E1.S form-factor. This high capacity CXL-based memory module is well-suited to sequential read applications - and is poised to be a game changer for Big Data applications.

CXL technology-based flash memory will be a cost-effective solution that addresses the pain point of increased system processing efficiency.

KIOXIA is an active member of the CXL consortium, the group that is accelerating the delivery of CXL technology-based flash solutions to the market. We are helping to drive education and awareness of these solutions and will continue to collaborate with server and hyperscale customers to further CXL evaluations and future adoption. We remain steadfast in our commitment to technology leadership in NAND flash memory and will help to drive CXL-based flash solutions to the market.

In every mention of a KIOXIA product: Product density is identified based on the density of memory chip(s) within the Product, not the amount of memory capacity available for data storage by the end user. Consumer-usable capacity will be less due to overhead data areas, formatting, bad blocks, and other constraints, and may also vary based on the host device and application. For details, please refer to applicable product specifications. The definition of 1KB = 2^10 bytes = 1,024 bytes. The definition of 1Gb = 2^30 bits = 1,073,741,824 bits. The definition of 1GB = 2^30 bytes = 1,073,741,824 bytes. 1Tb = 2^40 bits = 1,099,511,627,776 bits.
