'''GDDR7'''是[[JEDEC]]制定的一种[[GDDR]]以及[[SDRAM]]標準，具有高[[带宽 (计算机)|带宽]]、[[双倍数据速率]]接口，主要用於[[显示卡]]、[[電子遊戲機]]領域。它是[[GDDR6]]的下一代標準。<br />

== 历史 ==<br />
<br />
* 2022年，[[三星集团]]宣布未來GDDR7将取代[[GDDR6|GDDR6X]] ，GDDR7可提供高达 36GT/s 的傳輸速度。 <ref>{{Cite web |title=Samsung announces 36 Gbps GDDR7 memory standard, aims to release V-NAND storage solutions with 1000 layers by 2030 |url=https://www.notebookcheck.net/Samsung-announces-36-Gbps-GDDR7-memory-standard-aims-to-release-V-NAND-storage-solutions-with-1000-layers-by-2030.659998.0.html |website=Notebookcheck |date=2022-10-06 |language=en |access-date=2023-06-30 |archive-date=2023-06-30 |archive-url=https://web.archive.org/web/20230630155011/https://www.notebookcheck.net/Samsung-announces-36-Gbps-GDDR7-memory-standard-aims-to-release-V-NAND-storage-solutions-with-1000-layers-by-2030.659998.0.html |dead-url=no }}</ref><br />
* <br />
* 2023年7月18日，三星宣布推出第一代GDDR7產品，其带宽比[[GDDR6]]（1.1TB/s）高40%（1.5TB/s），能效提高20%。 <ref>{{Cite web |title=Samsung develops industry's first GDDR7 DRAM with 1.5 TBps bandwidth |url=https://www.notebookcheck.net/Samsung-develops-industry-s-first-GDDR7-DRAM-with-1-5-TBps-bandwidth.735158.0.html |website=Notebookcheck |date=2023-07-19 |language=en |access-date=2023-07-31 |archive-date=2023-07-31 |archive-url=https://web.archive.org/web/20230731044229/https://www.notebookcheck.net/Samsung-develops-industry-s-first-GDDR7-DRAM-with-1-5-TBps-bandwidth.735158.0.html |dead-url=no }}</ref><br />
* 2024年3月5日，JEDEC发布GDDR7显卡内存的正式标准和规范。 <ref>{{Cite web |title=JEDEC Publishes GDDR7 Graphics Memory Standard {{!}} JEDEC |url=https://www.jedec.org/news/pressreleases/jedec-publishes-gddr7-graphics-memory-standard |website=www.jedec.org |access-date=2024-03-05 |archive-date=2025-01-28 |archive-url=https://web.archive.org/web/20250128235438/https://www.jedec.org/news/pressreleases/jedec-publishes-gddr7-graphics-memory-standard |dead-url=no }}</ref><br />

== 技术 ==<br />
GDDR7增加了[[纠错码]]，可以進行错误检查和[[内存刷洗]]。 <ref name="micronComputex24">{{Cite web |title=Micron's GDDR7 Chip Smiles for the Camera as Micron Aims to Seize Larger Share of HBM Market |url=https://www.anandtech.com/show/21434/microns-gddr7-chip-smiles-for-the-camera-as-micron-aims-to-seize-huge-share-of-hbm-market- |website=www.anandtech.com |last=Shilov |first=Anton |access-date=2024-06-09 |archive-date=2024-12-23 |archive-url=https://web.archive.org/web/20241223232341/https://www.anandtech.com/show/21434/microns-gddr7-chip-smiles-for-the-camera-as-micron-aims-to-seize-huge-share-of-hbm-market- |dead-url=no }}</ref><br />
<br />
GDDR7数据速率为 32{{Spaces}}Gbps/pin，而一些[[运行内存]]制造商可以將速率提高到 36{{Spaces}}Gbps/pin。 <ref name="jedecAnand24">{{Cite web |title=JEDEC Publishes GDDR7 Memory Spec: Next-Gen Graphics Memory Adds Faster PAM3 Signaling & On-Die ECC |url=https://www.anandtech.com/show/21287/jedec-publishes-gddr7-specifications-pam3-ecc-higher-density |website=www.anandtech.com |last=Smith |first=Anton Shilov, Ryan |access-date=2024-06-09 |archive-date=2025-01-19 |archive-url=https://web.archive.org/web/20250119183439/https://www.anandtech.com/show/21287/jedec-publishes-gddr7-specifications-pam3-ecc-higher-density |dead-url=no }}</ref><br />
