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. |

Addendum No. 1 to JESD79-3 - 1.35 V DDR3L-800, DDR3L-1066, DDR3L-1333, DDR3L-1600, and DDR3L-1866This is a minor editorial revision, the differences between revisions can be found on page 17 of the document. |
JESD79-3-1A.01 | May 2013 |
The JESD79-3 document defines DDR3L SDRAM, including features, functionalities, AC and DC characteristics, packages, and ball/signal assignments with the exception of what is stated within this standard. The purpose of this standard is to define the DDR3L specifications that supersede the DDR3 specifications as defined in JESD79-3. The use of DDR3-800, DDR3-1066, DDR3-1333, DDR3-1600, and DDR3L-1866 titles in JESD79-3 are to be interpreted as DDR3L-800, DDR3L-1066, DDR3L-1333, DDR3L-1600, and DDR3L-1866 respectively, when applying towards DDR3L definition; unless specifically stated otherwise.

Addendum No. 3 to JESD79-3, 3D STACKED SDRAM |
JESD79-3-3 | Dec 2013 |
This addendum to JESD79-3 defines the 3DS DDR3 SDRAM specification, including features, functionalities, AC and DC characteristics, packages, and ball/signal assignments. The purpose of this specification is to define the minimum set of requirements for compliant 8Gbit through 64Gbit x4 and x8 3DS DDR3 SDRAM devices. This document was created based on the E revision of the DDR standard (JESD79). Each aspect of the changes for 3DS DDR3 SDRAM operation was considered. Committee(s): JC-42.3 Free download.

STANDARD MANUFACTURER'S IDENTIFICATION CODE |
JEP106BL | Feb 2025 |
The manufacturers identification code is defined by one or more 8 bit fields, each consisting of 7 data bits plus 1 odd parity bit. The manufacturers identification code is assigned, maintained and updated by the JEDEC Office. The intent of this identification code is that it may be used whenever a digital field is required, e.g., hardware, software, documentation, etc. To make a request for an ID Code please go to https://www.jedec.org/standards-documents/id-codes-order-form Free download.
