Working on standardizing the NAND flash memory interface, The Open NAND Flash Interface (ONFI) Working Group unveiled its first specification for that common integration with consumer electronics, computing platforms and industrial systems.

According to the group, the chip-level standard interface simplifies flash controller design and facilitates the integration of a wide range of NAND flash components into diverse end-use applications.

The ONFI 1.0 specification aims to define NAND device behavior, such as command and register sets, pin-out, electrical parameters and packaging. In addition, the group said, the specification provides NAND flash with the ability to identify itself and provide key characteristics such as memory layout, timing support, and enhanced features to the controller, via a standardized protocol.

This self-describe capability expands the range of NAND flash components that the application can efficiently accommodate, ONFI claimed. This also allows support for new flash components with minimal software changes, thus shortening qualification cycles and improving time-to-market for original design manufacturers and original equipment manufacturers.
