Samsung develops GDDR6 DRAM with 24Gbps speed for graphics cards

gddr6-d-3

Samsung said Thursday it has developed a new GDDR6 (graphics double data rate) DRAM with a data transfer rate of 24 gigabits per second (Gbps).

A premium graphics card that packs the chips supports a data processing speed of up to 1.1 terabytes (TB), which is equivalent to processing 275 movies in Full HD resolution within a second, according to the South Korean tech giant.

Samsung said the DRAM consisted of 16Gb chips using its third-generation 10nm process node, which also includes extreme ultraviolet (EUV) lithography during their manufacture.

The company also applied high-k metal gates, or the use of metals in addition to silicon dioxide to make the gate hold more charge, on the DRAM.

Samsung said this allowed its latest DRAM to run more than 30% faster than its 18Gbps GGDR6 DRAM predecessor.

The DRAM follows the latest GDDR6 DRAM standards set by the Joint Electron Device Engineering Council (JEDEC) __ the global memory chip standardizing body __ so that AI and graphics accelerator vendors can easily adapt it for their products, the company said.

Samsung said it is also adopting dynamic voltage switching to increase the power efficiency of the DRAM, reducing the operating voltage to 1.1V from the previous lowest rate of 1.35V, extending battery life in notebooks.

The company said it will begin verifying the DRAM with a major GPU customer for their next-generation system this month.

The high-performance graphics DRAM market is expected to grow at double-digit rates every year, Samsung noted, adding that it expects the new chip to be applied in PCs, notebooks and game consoles, as well as high-performance computing. electric vehicles and autonomous vehicles .
