DDR2 SDRAM STANDARD |
JESD79-2F | Nov 2009 |
This comprehensive standard defines all required aspects of 256Mb through 4Gb DDR2 SDRAMs with x4/x8/x16 data interfaces, including pinout, addressing, functional description, features, ac and dc parametrics, truth tables, and packages. Standard JESD79-2 uses a SSTL_18 interface, which is described in another JEDEC standard called JESD8-15. The purpose of this Standard is to define the minimum set of requirements for compliant devices 256Mb through 4Gb, x4/x8/x16 DDR2 SDRAMs. System designs based on the required aspects of this specification will be supported by all DDR2 SDRAM vendors providing compliant devices. Changes between versions is indicated in Annex A. Item 1778.01 Free download. Registration or login required. |

DDR3 SDRAM STANDARD |
JESD79-3F | Jul 2012 |
This document defines the DDR3 SDRAM standard, including features, functionalities, AC and DC characteristics, packages, and ball/signal assignments. The purpose of this Standard is to define the minimum set of requirements for JEDEC compliant 512 Mb through 8 Gb for x4, x8, and x16 DDR3 SDRAM devices. This document was created based on the DDR2 standard (JESD79-2) and some aspects of the DDR standard (JESD79). Each aspect of the changes for DDR3 SDRAM operation were considered and approved by committee ballots). The accumulation of these ballots were then incorporated to prepare this standard (JESD79-3), replacing whole sections and incorporating the changes into Functional Description and Operation. Item 1627.14 Patents(): A complete list of Assurance/Disclosure Forms is available to JEDEC members in the Members Area. Non-members can obtain individual Assurance/Disclosure Forms on request from the JEDEC office. Committee(s): JC-42.3 Available for purchase: $247.00 Add to Cart Paying JEDEC Members may login for free access. |
