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.

POD125 - 1.25 V PSEUDO OPEN DRAIN I/O	JESD8-30A.01	Jun 2022
Editorial Terminology Update. 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.
Temperature Range and Measurement Standards for Components and Modules	JESD402-1B	Sep 2024
This document specifies standard temperature ranges that may be used, by way of referencing JESD402-1, in other standards, specifications, and datasheets when defining temperature related specifications. Committee(s): JC-42 Free download. Registration or login required.
NEAR-TERM DRAM LEVEL ROWHAMMER MITIGATION	JEP300-1	Mar 2021
RAM process node transistor scaling for power and DRAM capacity has made DRAM cells more sensitive to disturbances or transient faults. This sensitivity becomes much worse if external stresses are applied in a meticulously manipulated sequence, such as Rowhammer. Rowhammer related papers have been written outside of JEDEC, but some assumptions used in those papers didn’t explain the problem very clearly or correctly, so the perception for this matter is not precisely understood within the industry. This publication defines the problem and recommends following mitigations to address such concerns across the DRAM industry or academia. Item 1866.01. Committee(s): JC-42 Free download.

Part Model Electrical Guidelines for Electronic-Device Packages – XML Requirements	JEP30-E100E	Aug 2024
This standard establishes the requirements for exchanging part data between part manufacturers and their customers for electrical and electronic products. This standard applies to all forms of electronic parts. It forms part of the Part Model XML Schema, which covers the parental structure for the electrical, physical, Electrical, assembly process classification data along with materials and substances that may be present in the supplied product or subproducts. This Guideline specifically focuses on the “Electrical” sub-section of the Part Model. For more information visit the main JEP30 webpage. Committee(s): JC-11, JC-11.2, JC-16 Free download.

POD135 - 1.35 V PSEUDO OPEN DRAIN I/O	JESD8-21C.01	Jun 2022
Editorial, Terminology Update. 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.
Graphics Double Data Rate 7 SGRAM Standard (GDDR7)	JESD239A	Sep 2024
This standard defines the Graphics Double Data Rate 7 (GDDR7) Synchronous Graphics Random Access Memory (SGRAM) specification, including features, functionality, package, and pin assignments. Committee(s): JC-42, JC-42.1 Free download. Registration or login required.
