Denali Software has a webcast about ONFi 2.0 in its archives. The webinar presents an overview of the ONFi 2.0 specification. Viewers of the webcast will learn about the benefits of the ONFi 2.0 specification, how it can increase system performance by reducing I/O time, and support scalable density applications.
The asynchronous NAND Flash interface was standardized with ONFi 1.0. ONFi 2.0 builds on ONFi 1.0 by adding a DDR, source-synchronous interface for high-speed data transfers to break the I/O bottleneck while providing backwards compatibility for NAND controllers that only support the asynchronous NAND interface.
