In addition to the announcement that it has distributed one million modules of its EUV-based DDR4 RAM, known as D1x, Samsung has published its future plans for the DDR5. EUV-based manufacturing is a key part of it, enabling a leaner, faster manufacturing process that also provides better yields.

In the statement, Samsung explained that "EUV technology reduces repetitive multi-patterning steps and improves patterning accuracy, enabling better performance and increased yields as well as reduced development times.". EUV stands for "extreme ultraviolet".

Samsung plans to build on the D1x process with D1a, a class 14 nm process with EUV layers, which should provide superior all-round experience. With the ability to reduce the use of multi-patterning, this should mean performance and much better yields. DDR5 should double the memory bandwidth, offer higher performance and capacity. For now, however, Samsung has not provided information on how many layers EUV will use its processes.

In order to use DDR5 RAM from next year onwards, you will need to purchase a new compatible motherboard. For now, there are no compatible models on the market, but they could arrive very soon.

Processor compatibility

AMD will provide support to the DDR5 from the fifth generation Ryzen series onwards. As for Intel, with the new Rocket Lake processors coming in 2021, some rumors state a lack of support for DDR5.

DDR5 will most likely be available on server systems before they can be used in consumer systems.
