GRAPHICS DOUBLE DATA RATE (GDDR5) SGRAM STANDARD	JESD212C	Feb 2016
This document defines the Graphics Double Data Rate 5 (GDDR5) Synchronous Graphics Random Access Memory (SGRAM), including features, functionality, package, and pin assignments. The purpose of this Standard is to define the minimum set of requirements for JEDEC standard compatible 512 Mb through 8 Gb x32 GDDR5 SGRAM devices. System designs based on the required aspects of this standard will be supported by all GDDR5 SGRAM vendors providing JEDEC standard compatible devices. Some aspects of the GDDR5 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. Item 1733.70B 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-42.3C Free download. Registration or login required.
GRAPHICS DOUBLE DATA RATE 6 (GDDR6) SGRAM STANDARD	JESD250B	Nov 2018
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 Specification 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). Item 1836.99D. Committee(s): JC-42.3C Free download. Registration or login required.
GRAPHICS DOUBLE DATA RATE (GDDR5X) SGRAM STANDARD	JESD232A	Aug 2016
The purpose of this standard is to define the minimum set of requirements for JEDEC standard compatible 4 Gb through 16 Gb x32 GDDR5X SGRAM devices. System designs based on the required aspects of this standard will be supported by all GDDR5X SGRAM vendors providing JEDEC standard compatible devices. Some aspects of the GDDR5X standard such as AC timings were not standardized. Some features are optional and therefore may vary among vendors. In all cases, vendor data sheets should be consulted for specifics. Item 1827.99C Committee(s): JC-42.3, JC-42.3C Free download. Registration or login required.
POD135 - 1.35 V PSEUDO OPEN DRAIN I/O	JESD8-21C	Jun 2019
This standard defines the dc and ac single-ended (data) and differential (clock) operating conditions, I/O impedance's, and the termination and calibration scheme for 1.35 V Pseudo Open Drain I/Os. The 1.35 V Pseudo Open Drain interface, also known as POD135, is primarily used to communicate with GDDR5 or GDDR5M SGRAM devices. Item 146.01B Committee(s): JC-16 Free download. Registration or login required.
POD125 - 1.25 V PSEUDO OPEN DRAIN I/O	JESD8-30A	Jun 2019
This standard defines the DC and AC single-ended (data) and differential (clock) operating conditions, I/O impedances, and the termination and calibration scheme for 1.25 V Pseudo Open Drain I/Os. The 1.25 V Pseudo Open Drain interface, also known as POD125, is primarily used to communicate with GDDR6 SGRAM devices. Committee(s): JC-16 Free download. Registration or login required.
