SAN JOSE, Calif. - The Open NAND Flash Interface (ONFI) Working Group, the organization dedicated to simplifying integration of NAND flash memory into consumer electronic devices, computing platforms, and industrial systems, has published the new ONFI 3.0 standard.
By using the non-volatile DDR2 (NV-DDR2) interface, the newly ratified standard reaches speeds of up to 400 megabytes (MB)/sec, doubling the current NAND interface transfer rates.
The previous ONFI 2.1 specification pushed performance levels to 166 megabytes per second (MB/s) to 200 MB/s.
Like previous ONFI standards, ONFI 3.0 is designed with simplicity in mind for NAND-based devices and is backwards compatible with previous ONFI standards. In future versions, ONFI 3.0 will also support the ECC Zero (EZ-NAND) interface, which removes burden of the host controller having to keep pace with the fast changing ECC requirements of NAND technology.
There are other benefits, which can be seen here.
The Open NAND Flash Interface is an industry working group made up of more than 80 companies that build, design-in, or enable NAND flash memory. The ONFI Working Group was formed in May 2006 and currently has more than 100 member companies. ONFI’s founding companies include Hynix Semiconductor, Intel, Micron, Phison, SanDisk, Sony and Spansion.
