First introduced in August of 2019, and then presented as a proposal to the JEDEC Subcommittee for Electrical Specifications and Command Protocols, the XFMEXPRESS XT2 is a new form factor for PCIe/NVMe devices. Featuring a combination of small size, speed and serviceability, its technology was developed to enhance next-gen mobile and embedded applications. The XFMEXPRESS XT2 is the first product to meet the spec of the JEDEC standard.

Kioxia Xfmexpress 2 2206XFMEXPRESS XT2 key features and benefits:

  • Game-changing serviceability
    It enables a new category of small storage devices that are to service or upgrade. By pairing a robust, compact package with removable storage functionality and flexibility, it helps diminish technical barriers and design constraints.

  • Mobile-friendly footprint
    The JEDEC XFM DEVICE Ver.1.0 form factor’s small size and low profile (14x18x1.4mm) offers a 252mm [2] footprint, optimizing the mounting space for compact host devices without sacrificing performance or serviceability. With this minimized z-height, the XFMEXPRESS XT2’s form factor is for thin and light notebooks and creates new design possibilities for next gen applications and systems.

  • Interface
    Designed for speed, it implements a PCIe 4.0 x 2 lanes, NVMe 1.4b interface. The XFMEXPRESS XT2’s industry-leading [3] performance capabilities and durable form factor provide a compelling alternative to other SSD form factors (such as M.2), enabling superior computing and entertainment experiences.

Recognizing the need for a new class of removable storage, Kioxia, inventor of flash memory, leveraged its extensive background in single package memory designs to develop the XFMEXPRESS XT2.” comments, Axel Stoermann, VP, memory marketing and engineering.We are planning to innovate and lead the way forward with more breakthrough storage solutions for complex design challenges in the future.

The company will demonstrate its XT2 solution live at Embedded World 2022 in Nurnberg, Germany from June 21-23 as well as the Flash Memory Summit 2022 from August 2-4 at the Santa Clara Convention Center, CA.
