DDR5
When JEDEC released its DDR5 specification (JESD79) back in 2020, the standard setting organization defined precise specs for modules with speed bins of up to 6400 MT/s, while leaving the spec open to further expansions with faster memory as technology progressed. Now, a bit more than three-and-a-half years later, and the standards body and its members are gearing up to release a faster generation of DDR5 memory, which is being laid out in the newly updated JESD79-JC5 specification. The latest iteration of the DDR5 spec defines official DDR timing specifications up to 8800 MT/s, as well as adding some new features when it comes to security. Diving in, the new specification outlines settings for memory chips (on all types of memory modules) with data transfer...
