samsung GDDR7 DRAM

 The official GDDR7 DRAM specs, the most recent version of the long-standing memory standard for graphics cards and other GPU-powered devices, were released by JEDEC on Tuesday. Memory capacity and bandwidth increases are combined in the latest generation of GDDR, with the latter being mainly driven by the memory bus's move to PAM3 signaling. In order to preserve the memory's effective reliability, the most recent graphics RAM standard also increases the number of channels per DRAM chip, introduces new interface training patterns, and incorporates on-die ECC.

High-speed memory design has advanced significantly with JESD239 GDDR7, according to JEDEC Board of Directors Chairman Mian Quddus. "The memory industry now has a new path to extend the performance of GDDR devices and drive the ongoing evolution of graphics and various high-performance applications with the shift to PAM3 signaling."

GDDR7 has been under development for a few years now. About a year ago, Cadence, a JEDEC member, disclosed that the memory technology uses PAM3 encoding as one of its validation methods. Since then, a number of memory makers have informed us that the final version of the memory is expected to be released in 2024, and JEDEC's announcement has essentially come at the perfect time.
