Standard for NAND flash device interface interoperability by JEDEC and ONFI

JEDEC Solid State Technology Association and the Open NAND Flash Interface Workgroup (ONFI) have announced the publication of JESD230 NAND Flash Interface Interoperability Standard (Package). This jointly developed document defines a standard for NAND flash device interface interoperability. JESD230 is available for free download from both www.jedec.org and www.onfi.org.

JESD230 addresses signaling descriptions, packages, definitions, abbreviations and conventions, and is backwards compatible with existing technologies to the greatest degree possible. The standard will help enable the design of interoperable systems that can support Asynchronous SDR, Synchronous DDR and Toggle DDR NAND flash devices.

“By joining forces to develop and publish JESD230, ONFI and JEDEC have responded to the industry’s need for interoperability among NAND vendors, which will enable even broader use of NAND flash in a wide variety of applications,” said Amber Huffman, senior principal engineer, Intel Storage Technologies Group and chairperson for the ONFI Workgroup Board of Directors.

Added Cecil Ho, Chairman of JEDEC’s JC-42.4 Subcommittee, “JEDEC is delighted to have collaborated with ONFI to develop and publish the first joint NAND Flash Interoperability Standard focused on packages, which we believe will be welcome news to NAND flash vendors and end users.”
