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.

WIDE I/O SINGLE DATA RATE (WIDE I/O SDR)	JESD229	Dec 2011
This standard defines the Wide I/O specification, including features, functionality, AC and DC characteristics, packages, and micropillar signal assignments. This standard covers the following technologies: Wide I/O. The purpose of this standard is to define the minimum set of requirements for JEDEC compliant, 1 Gb through 32 Gb SDRAM (monolithic density) devices with 4, 128b wide channels using direct chip-to-chip attach methods between 1 to 4 memory devices and a controller device.
