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 2027, it is a type of DDR SDRAM, and will be the successor to DDR5. It will have a speed of 8,800–17,600 MT/s, [2] will have four memory channels, and a bandwidth up to 134.4 GB/s. [3] It may also possibly have 4×24-bit sub-channel architecture. [4]

Efficiency

It will have CAMM2 form factor for efficiency, especially for laptops and compact devices. [4] It will also have Decision Feedback Equalization. [5]
