Samsung mass producing 800MHz GDDR3 chips

Posted on Saturday, February 14 2004 @ 13:02:08 CET by


Samsung has announced mass production of its Graphics Double Data Rate 3 (GDDR3) memory capable of doing clock speeds of up to 800MHz.
The GDDR3 256Mb graphics memory devices manufactured by Samsung are clocked at 500MHz, 600MHz, 700MHz and 800MHz speeds effectively providing 1000Mb/s, 1200Mb/s, 1400Mb/s and 1600Mb/s per pin bandwidth. Such memory will enable high speed 256MB and 512MB graphics cards as well as power efficient 128MB notebook solutions.

To allow speeds beyond 1.0GHz Samsung used a number of technologies developed for DDR-II and GDDR2 memories, such as On-Die Termination (ODT), Output Driver Strength adjustment by EMRS, Calibrated output drive, Pseudo Open drain compatible inputs/outputs and some other.

Samsung’s GDDR3 memory chips are packaged in 144-ball FBGA package and require 1.9V power supply for device operation and 1.9V power supply for I/O interface.
“It is a lower cost, lower power and faster alternative to equivalent density stacked solutions today,” the representative for Samsung said.

“With the aid of high-speed memory technology such as Samsung’s new GDDR3 graphics memory, NVIDIA will continue to advance graphics technology at an incredible pace so game developers have the freedom to stretch the limits of the cinematic computing experience,” an NVIDIA’s spokesperson said.

In mid-September we reported that Samsung supplied a batch of its high-speed 1.60GHz memory chips to NVIDIA Corporation for NV40 testing purposes. Peak theoretical bandwidth of 1600MHz memory on 256-bit bus is mind-blowing 51.2GB/s, therefore, in case NVIDIA’s next-generation high-end GPUs work with such memory, there will be a major performance improvement over current generation of high-performance graphics cards.
