WebFlash memory is an electronic non-volatile computer memory storage medium that can be electrically erased and reprogrammed. The two main types of flash memory, NOR flash and NAND flash, are named for the … WebCFI flash controller IP. Provides two modes of operation - simple (Wishbone bus straight through to flash bus, essentially, but with 32-bit word read capability, allowing XIP - execute in place - for 32-bit processors) and a "CFI engine" mode, which aims to simplify interfacing with a CFI flash. Only implements asynchronous flash bus interface.

The Common Flash Memory Interface (CFI) is an open standard jointly developed by AMD, Intel, Sharp and Fujitsu. It is implementable by all flash memory vendors, and has been approved by the non-volatile-memory subcommittee of JEDEC. The goal of the specification is the interchangeability of flash memory devices offered by different vendors. The developer is able to use one driver for different flash products by reading identifying information from the flash chip. Webflash array return the ASCII equivalent “Q,” “R,” and “Y,” then the device is CFI-compliant. Although there are other configuration possibilities, there are currently three CFI array configurations that are of primary interest. These configurations must be tested for and accounted for in the software. These configurations are:

WebCommon Flash Interface (CFI) is primarily used by Cypress parallel NOR flash, and by S25FL-P, S25FL-S, S25FS-S Serial NOR flash memory products only.
