JEDEC Publishes GDDR7 Memory Spec: Next-Gen Graphics Memory Adds Faster PAM3 Signaling & On-Die ECC
v on March 6, 2024 9:00 AM EST JEDEC on Tuesday published the official specifications for GDDR7 DRAM, the latest iteration of the long-standing memory standard for graphics cards and other GPU-powered devices. The newest generation of GDDR brings a combination of memory capacity and memory bandwidth gains, with the later being driven primarily by the switch to PAM3 signaling on the memory bus.
JEDEC on Tuesday published the official specifications for GDDR7 DRAM, the latest iteration of the long-standing memory standard for graphics cards and other GPU-powered devices. The latest graphics RAM standard also boosts the number of channels per DRAM chip, adds new interface training patterns, and brings in on-die ECC to maintain the effective reliability of the memory. “With the shift to PAM3 signaling, the memory industry has a new path to extend the performance of GDDR devices and drive the ongoing evolution of graphics and various high-performance applications.”
