JEDEC Solid State Technology Association, the global leader in standards development for the microelectronics industry, today announced the publication of JESD233: XFM Embedded and Removable Memory Device (XFMD) standard. XFMD (XFM stands for Crossover Flash Memory) is a new universal data storage media providing an NVMe over PCI Express 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 Specifications and Command Protocols, JESD233 is available for download from the
JEDEC website.
JESD233 XFMD is a removable, versatile memory solution intended for use in a wide range of applications that require an easy device exchange. Examples include IoT devices, automotive applications, notebook PCs, gaming consoles, video recording devices (drones, surveillance systems, etc.), Extended Reality (AR, VR, MR), and more.
To maximize connectivity between the host and the device, JESD233 XFMD leverages industry-leading standards from PCI-SIG and NVM Express, Inc. The PCI Express interface provides fundamental bus connectivity and NVM Express serves as the higher level protocol for accessing the non-volatile media as a low-latency logical storage device.
