In brief: Similar other retentivity manufacturers, Samsung doesn't look DDR5 to become mainstream earlier 2023. In the meantime, the South Korean visitor is building monster-sized DDR5-7200 modules for the information center, starting with a 512-gigabyte one that will enter mass production by the cease of this year.

The Hot Chips conference is even so in flux, and Samsung is using the occasion to tease a special DDR5 memory module with a total capacity of over 512 gigabytes. This is a natural development from the current DDR4 modules that go up to 256 gigabytes in size, merely it'due south also a story of numerous challenges that the visitor needed to overcome in order to get hither.

The DDR5-7200 module was starting time announced in March, and the memory chips are made using a High-K Metallic Gate (HKMG) process that reduces leakage and pushes the limits of what DRAM tin achieve in terms of performance. It's also a first for DRAM, although CPU manufacturers similar Intel have been using this process engineering science since 2007 when the company used information technology for its Penryn Core two processors.

While JEDEC has however to ratify a DDR5-7200 standard, Samsung didn't reveal the latencies at which this new memory module operates. All we know is that information technology volition offer 40 percent higher performance when compared to previous Samsung DDR4 RDIMM while operating at just one.1 volts. This results in a 30 percent increase in power efficiency thanks in no small office to the integrated Ability Management IC (PMIC) and a much-improved DRAM bus.

In terms of structure, Samsung says it stacks no less than eight DDR5 dies in less space than it needed for just half as many DDR4 dies. This was achieved past thinning the dies as well every bit the through-silicon via (TSV) connection between them, which led to a significant reduction in the overall height of the silicon package. The more meaty size prompted the company to improve the cooling capabilities with lower airflow impedance.

Information technology'due south worth noting that this RAM module is intended for the server marketplace, and equally such we won't be seeing such monstrous sized (and expensive) memory in consumer retail stores. It does, however, signal that 64-gigabyte modules are on the mode, for consumers who will want to play games from a RAM deejay as well every bit professionals who demand them for workstation-class PCs.

Samsung'south 512-gigabyte DDR5-7200 module is expected to enter mass production past the end of this year.
