512GB of Super-fast DDR5 Memory Marks New Record

There's no such thing as too much RAM? Thanks to HKMG technology, Samsung has managed to develop ultra-fast 512GB DDR5 modules.

  • Samsung has developed 512GB DDR5 memory modules thanks to HKMG technology.

RAM that can hold an entire game? Samsung has developed DDR5 memory modules with a considerable capacity of 512 GB, which are also fast and energy-efficient. This has been achieved thanks to the technology of chip manufacturing technology using a material known as HKMG, previously used successfully by this manufacturer in GDDR6 memories. They will be used in data centers and supercomputers.

As Samsung states in a recent press release, the creation of a single DDR5 module with such a large capacity is possible thanks to TSV layering technology. HKMG enables the company to stack eight layers of 16 Gb (2 GB) DRAM chips. In this way, high speeds of up to 7200 Mbps can be achieved. This is twice as fast as in the case of DDR4. Power consumption can be reduced by up to 13%, which will be particularly important in the server sector, where energy efficiency is often crucial.

We do not know when DDR5 512 GB modules may be available for sale - they still have to undergo verification tests and certification. At the end of the year, the Alder Lake-S platform is expected to be released on the consumer market, which will support DDR5 memories.

HKMG (High-k Metal Gate)

Technology that is based on the use of material with a so-called high dielectric constant in transistors, which reduces current leakage. This makes the IC more energy efficient, allows for greater miniaturization and higher performance.
