I am attempting to use a SPI NOR flash memory IC that is said to support CFI (Common Flash Interface) and the JEDEC flash command set. This sounds great however I have been unable to find any documentation on what the JEDEC command set is specifically or how to interface with this device.

Does anybody know of a reference for this information?


The CFI Specification can be downloaded from jedec.org.

  • \$\begingroup\$ These are vendor defined. The Query structure gives you the algorithm ID, the actual protocol can usually be found on the vendor site. \$\endgroup\$ – Simon Richter Nov 25 '15 at 10:58
