JEDEC Published JESD233 XFM Embedded and Removable Memory Device (XFMD) Standard

JEDEC Solid State Technology Association announced the publication of the JESD233: XFM Embedded and Removable Memory Device (XFMD) standard.

XFMD (XFM stands for Crossover flash Memory) is a new universal storage media providing an NVMe over PCIe interface in a small, thin form factor. The device is designed to bring replaceable storage to devices typically soldered down in IoT devices and embedded applications. Developed by JEDEC’s JC-64.1 Subcommittee for Electrical specs and Command Protocols, JESD233 is available for download from the JEDEC website (registration required).

JESD233 XFMD is a removable, versatile memory solution intended for use in a range of applications that require a device exchange. Examples include IoT devices, automotive applications, notebook PCs, gaming consoles, video recording devices (drones, surveillance systems, etc.), Extended Reality (AR, VR, MR).

To maximize connectivity between the host and the device, JESD233 XFMD leverages industry standards from PCI-SIG and NVM Express Inc. The PCIe interface provides fundamental bus connectivity and NVMe serves as the higher level protocol for accessing the non-volatile media as a low-latency logical storage device.

“The development of JEDEC XFMD is a prime example of JEDEC’s dedication to developing new and innovative standards to serve the industry and, ultimately, consumers,” said Mian Quddus, chairman, JEDEC. “XFMD is intended to minimize technical barriers in new product designs by offering ease of use and robust capabilities serving a variety of applications.“

“We are convinced that the XFM Embedded and Removable Memory Device (XFMD) standard will be used as a game changer for semi-removable storage in many electronic and IOT devices, taking advantage of its balanced performance, small size, and easy maintenance,” said Atsushi Inoue, senior director, memory division, Kioxia Corp.

“MediaTek is proud to have collaborated with JEDEC members to advance the development of the Embedded and Removable Memory Device (XFMD) standard, which provides an attractive option for high-performance storage in embedded devices,” said Harrison Hsieh, senior GM, silicon product development, MediaTek, Inc. “Platform developers and device makers can easily adopt XFMD with minimal effort to enable new, expandable storage options for end users.”
