The '''Common Flash''' memory '''Interface''' ('''CFI''') is an open standard jointly developed by [[AMD]], [[Intel]], [[Sharp Corporation|Sharp]] and [[Fujitsu]]. (AMD has since sold its flash memory products division to Spansion.) An overview about the specification is available at [http://www.spansion.com/Support/AppNotes/CFI_Spec_AN_03.pdf Spansion]. It is an open standard, which means it is freely implementable by all [[flash memory]] vendors, and has been approved by the non-volatile memory subcommittee of [[JEDEC]]<ref>{{cite web |url=http://www.jedec.org/download/search/jesd68-01.pdf |title=JEDEC Standard: Common Flash Interface |publisher=JEDEC|date=September 2003}}</ref>. The idea behind was the interchangeability of current and future flash memory devices offered by different vendors. The developer is able to use one driver for different flash products by reading identifying information out of the flash chip itself.
