LPDDR6 reminiscence customary introduced as DDR5 DRAM takes over
The JEDEC Stable State Know-how Affiliation has introduced the LPDDR6 reminiscence customary, even because the reminiscence market transitions from DDR4 to DDR5.
Final 12 months, market analysts anticipated that the DDR5 reminiscence customary for desktops and the LPDDR5 (low-power DDR5) reminiscence customary for notebooks can be conflated, and that could be what has occurred right here. Formally, the brand new customary is called the brand new JESD209-6 LPDDR6 customary, the group mentioned.
The usual operates “with a decrease voltage and low energy consumption succesful VDD2 provide,” JEDEC mentioned, with out specifying extra. (JEDEC fees $446 for the total specification.) LPDDR6 system density will differ, nonetheless, from 4 Gbits to 64 Gbits, it mentioned.
JEDEC’s press launch goes into extra options of the specification, together with that there are two sub-channels per die, with 12 sign traces. Tom’s {Hardware}, citing a 2024 Synopsys/JEDEC presentation issued earlier than the specification was finalized, signifies that the LPDDR5 reminiscence knowledge charges may run from 10.667Gbps to 14.4Gbps, with bandwidth of 32GBps. Reminiscence analysts TrendForce be aware that the present, slower LPDDR5X helps knowledge charges from 6.7Gbps to 10.667Gbps — mainly giving LPDDR6 one other gear.
JEDEC’s announcement was supported by Micron, SK Hynix, and Samsung, amongst others — the world’s high reminiscence makers. TrendForce has mentioned it expects DDR6 reminiscence to be introduced later in 2025 and probably require the usage of LPCAMM2 modules, in a break from earlier generations.
In the meantime, as DDR4 reminiscence manufacturing winds down, DDR4 reminiscence costs are starting to soar. It seems like a DDR5 transition is imminent, and even then reminiscence makers want to see the trade migrate to the dearer DDR6 customary as rapidly as attainable.
