ARLINGTON, Va., USA – NOVEMBER 18, 2024 – JEDEC® Solid State Technology Association, the global leader in the development of standards for the microelectronics industry, today announced the publication of JESD230G: NAND Flash Interface Interoperability Standard.  JESD230G introduces speeds of up to 4800 MT/s, as compared to 400 MT/s in the first version of JESD230 published in 2011.  Also, JESD230G adds a separate Command/Address Bus Protocol (SCA), delivering enhanced throughput and efficiency by allowing hosts and NAND devices to take maximum advantage of the latest interface speeds.  JESD230G is available for free download from the JEDEC website.

“JEDEC is excited to release JESD230G,” said David Landsman, Distinguished Engineer at Western Digital and Chair of the JEDEC NAND TG.  He added, “This version of JESD230 further advances the capabilities of NAND flash devices to meet the growing demands of their expanding range of applications and continues the JEDEC tradition of building interoperable ecosystems through open industry standards.”

“JEDEC, with the collaboration of ONFI and Toggle Mode companies, has continued to provide the NAND industry with a NAND Flash interoperability standard that enables the broad use of NAND in performance-demanding applications of today,” said Dan Loughmiller, Micron Director for NAND Enablement and ONFI Board Chair. “The JESD230G specification enables even higher-performing NAND devices with a 4.8GT/s NAND interface definition and revolutionary new Separate Command Address (SCA) protocol. Tremendous results from the hard work and effort of the members of the NAND Task Group.”
