ONFI Releases 3.2 Standard

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, published the new ONFI 3.2 standard.

The ONFI 3.2 standard extends the non-volatile DDR2 (NV-DDR2) interface from 400 MB/s to 533 MB/s, providing a performance boost of up to 33% for high performance applications enabled by solid-state drives.

The ONFI 3.2 standard includes two BGA package definitions that provide four concurrent channels of NAND, allowing for over 2 GB/s of performance out of a single NAND package. The package definitions have been developed in collaboration with the JEDEC Solid State Technology Association, ensuring interoperability across all NAND vendors.

Additionally, ONFI has begun work on its next generation specification ? ONFI 4.0 ? targeting speeds up to 800 MB/s. While pushing the envelope of performance, ONFI 4.0 is also focused on reducing power by lowering voltages and employing other power saving measures.
