Graphics Double Data Rate (GDDR6) SGRAM Standard	JESD250D	May 2023
This document defines the Graphics Double Data Rate 6 (GDDR6) Synchronous Graphics Random Access Memory (SGRAM) specification, including features, functionality, package, and pin assignments. The purpose of this Standard is to define the minimum set of requirements for 8 Gb through 16 Gb x16 dual channel GDDR6 SGRAM devices. System designs based on the required aspects of this standard will be supported by all GDDR6 SGRAM vendors providing compatible devices. Some aspects of the GDDR6 standard such as AC timings and capacitance values were not standardized. Some features are optional and therefore may vary among vendors. In all cases, vendor data sheets should be consulted for specifics. This document was created based on some aspects of the GDDR5 Standard (JESD212). Committee(s): JC-42.3C Free download.

Item 1600.41, Terminology Update This document defines the Graphics Double Data Rate 4 (GDDR4) Synchronous Graphics Random Access Memory (SGRAM) standard, including features, functionality, package, and pin assignments. This scope may be expanded in future to also include other higher density devices. Committee(s): JC-42.3 JESD21-C Solid State Memory Documents Main Page Free download. Registration or login required.
DRIVER SPECIFICATIONS FOR 1.8 V POWER SUPPLY POINT-TO-POINT DRIVERS	JESD8-17	Nov 2004
This material is intended to be reflected in supplier specifications for point to point DDR devices ranging from 400 Mb/s to 800 Mb/s operation. It is a method to specify driver impedance with something other than a number that does not nec-essarily define how it operates in a real net This standard addresses this issue using net lengths and specifies how much uncertainty can exist in the data for each speed supported.
