The '''Common Flash Memory Interface''' ('''CFI''') is an open standard jointly developed by [[Advanced Micro Devices|AMD]], [[Intel]], [[Sharp Corporation|Sharp]] and [[Fujitsu]]. It is 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 |archiveurl=httphttps://waybackweb.archive.org/web/20090306191719/http://www.jedec.org/download/search/jesd68-01.pdf |archivedate=6 March 2009 |title=JEDEC Standard: Common Flash Interface |publisher=JEDEC|date=September 2003}}</ref> 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.

Each flash memory device contains the following information: memory size, byte and word configuration, block configuration, and voltage and timing data.
