SPECIALITY DDR2-1066 SDRAM	JESD208	Nov 2007
This document defines the Specialty DDR2-1066 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 JEDEC compliant 256 Mb through 4 Gb for x4, x8, and x16 Specialty DDR2-1066 SDRAM devices. Committee(s): JC-42.3 Free download. Registration or login required.
DOUBLE DATA RATE (DDR) SDRAM STANDARD	JESD79F	Feb 2008
This comprehensive standard defines all required aspects of 64Mb through 1Gb DDR SDRAMs with X4/X8/X16 data interfaces, including features, functionality, ac and dc parametrics, packages and pin assignments. This scope will subsequently be expanded to formally apply to x32 devices, and higher density devices as well The purpose of this Standard is to define the minimum set of requirements for JEDEC compliant 64Mb through 1Gb, X4/X8/X16 DDR SDRAMs. System designs based on the required aspects of this specification will be supported by all DDR SDRAM vendors providing JEDEC compliant devices.

Addendum No. 1 to JESD209A, LOW POWER DOUBLE DATA RATE (LPDDR) SDRAM, 1.2 V I/O.	JESD209A-1	Mar 2009
This document defines the Low Power Double Data Rate (LPDDR) SDRAM 1.2 V I/O, including AC and DC operating conditions, extended mode register settings, and I-V characteristics. The purpose of this Standard is to define the minimum set of requirements for JEDEC compliant 64 Mb through 2 Gb for x16 and x32 Low Power Double Data Rate SDRAM devices with 1.2 V I/O. System designs based on the required aspects of this specification will be supported by all LPDDR SDRAM vendors providing compliant devices. Committee(s): JC-42.6 Free download. Registration or login required.
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 Committee(s): JC-42, JC-42.3 Free download. Registration or login required.
LOW POWER DOUBLE DATA RATE (LPDDR) SDRAM STANDARD	JESD209B	Feb 2010
This standard defines the Low Power Double Data Rate (LPDDR) SDRAM, including features, functionality, AC and DC characteristics, packages, and pin assignments. This scope may be expanded in future to also include other higher density devices. The purpose of this document is to define the minimum set of requirements for JEDEC compliant 64Mb through 2Gb for x16 and x32 Low Power Double Data Rate SDRAM devices. System designs based on the required aspects of this standard will be supported by all LPDDR SDRAM vendors providing compliant devices. (JESD209 was originally numbered as JESD79-4 May 2006 to August 2007, corrected to JESD209 09/17/2007). Patents(): See Document Committee(s): JC-42.3, JC-42.6 Free download.
