The JEDEC Solid State Technology Association, formerly known as the Joint Electron Devices Engineering Council, has made an announcement that should surprise nobody: it's working on a new memory standard, DDR5, which promises to be faster and more efficient than the current-generation DDR4.

According to JEDEC, DDR5 (Double Data Rate 5) will offer double the bandwidth and memory density over the existing DDR4 standard, along with improved channel efficiency. In short, and to nobody's surprise, DDR5 will be to DDR4 what DDR4 was to DDR3 and so on back through the standards until DDR gives way to the original single data rate RAM of the olden days. At the same time, the organisation announced that it is working on a standard for non-volatile hybrid memory dubbed NVDIMM-P (Non-Volatile Dual Inline Memory Module, Persistent), which would give servers the ability to store data in RAM between reboots.

'Increasing server performance requirements are driving the need for more advanced technologies, and the standardisation of next generation memory such as DDR5 and the new generation persistent modules NVDIMM-P will be essential to fulfilling those needs,' claimed Mian Quddis, chair of the JEDEC board, at the announcement. 'Work on both standards is progressing quickly, and we invite all interested engineers worldwide to visit the JEDEC website for more information about JEDEC membership and participation in JEDEC standards-setting activities.'

With AMD having only adopted DDR4 this year, though, it'll be a while before we see DDR5 at the consumer level: the JEDEC Association has stated it doesn't expect to even publish the standard, nor the NVDIMM-P design standard, until some time in 2018.
