DDR6 SDRAM

Double Data Rate 6 Synchronous Dynamic Random-Access Memory is the next planned type of synchronous dynamic random-access memory with a high-bandwidth interface. Scheduled to release in 2028, it is a type of DDR SDRAM, which will be the successor to DDR5. It will have a speed of 8,800–17,600 MT/s, four 24-bit wide memory channels, and a bandwidth up to 134.4 GB/s. DDR6 is expected to add optional 3D DRAM support.

Double Data Rate 6 Synchronous Dynamic Random-Access Memory (DDR6 SDRAM) is the next planned type of synchronous dynamic random-access memory with a high-bandwidth ("double data rate") interface. Scheduled to release in 202823, it is a type of DDR SDRAM, which will be the successor to DDR5. It will have a speed of 8,800–17,600 MT/s,4 four 24-bit wide memory channels56, and a bandwidth up to 134.4 GB/s.7 DDR6 is expected to add optional 3D DRAM support.8

Efficiency

It will have CAMM2 form factor for efficiency, especially for laptops and compact devices.5 It will also have Decision Feedback Equalization.9
