COMMON FLASH INTERFACE (CFI): |
JESD68.01 | Sep 2003 |
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. This allows device-independent, JEDEC ID-independent, and forward- and backward-compatible software support for the specific flash families. It allows flash vendors to standardize their existing interfaces for long-term compatibility. The changes for this minor revision are indicated in Annex A on page 11.

CONFIGURATIONS FOR SOLID STATE MEMORIES:Status: Under RevisionSections in this document may be under revision at any time. |
JESD21-C | Jan 2003 |
This revision of JESD21 is substantially different from previous issues because it reflects advancement in semiconductor technology and computer design needs. A new class of memory devices, the multiport DRAM (MPDRAM) C also know as 'Video Ram' because of the most common application for the devices C is represented. A new family of SRAMs which addresses the increasing need for high speed is introduced. Additional families of devices in the SOJ and Zip packages are included. The material in this revision is organized primarily by function (ROM, EPROM, SRAM, DRAM, etc.) rather than by technology and word length. Pinouts for SIMM and DIMM are included along with presence detect schemes. A current set of terms has also been included. JESD21-C is a compilation of all memory device standards that have been developed by the JC-42 Committee and approved by the JEDEC BoD from September 1989 to present. This latest issue has changed to a loose-leaf format and comes in a three-ring binder so that new drawings can be added without requiring a new publication. Time of publication of the material is identified by release number, i.e., if marked Release 8, this item was approved and released in 1998, if marked Release 13, this item was approved and released in 2003.
