JEDEC JESD230G Enhanced NAND Flash Interface Standard with Increased Speeds and Efficiency

JEDEC Solid State Technology Association announced the publication of JESD230G: NAND Flash Interface Interoperability Standard.

JESD230G introduces speeds of up to 4,800MT/s, as compared to 400MT/s in the 1st 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, Western Digital Corp., and chair, 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, director, NAND enablement, Micron 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.”
