The developer is able to use one driver for different flash products by reading identifying information from the flash chip. Der Nutzen von SFDP spiegelt den des Common Flash Interface (CFI) für paralleles Flash wider. The Nios II Flash Programmer can be used to program the following types of memory: • Common flash interface (CFI)-compliant flash memory—CFI is an industry standard that provides a common, vendor-independent interface to flash memory devices. (See the Memory Heuristics Flowchart included in Appendix A1.) Common Flash Interface (CFI) is a published, standardized data structure that may be read from a flash memory device. It allows flash vendors to standardize their existing interfaces for long-term compatibility. The Common Flash Interface (CFI) specification outlines a device and host system software interrogation handshake that allows specific software algorithms to be used for entire families of devices. History. This allows device-independent, JEDEC ID-independent, and forward- and backward-compatible software support for the specific flash families. View all product details Most Recent Track It. This publication is a companion document to the Common Flash Interface (CFI) standard, JESD68, which outlines the device and host system software interrogation handshake.
