Leading Memory Makers Show DDR4 Prototypes at ISSCC.

DDR4 Memory Types Gets Closet with ISSCC Demos

Leading manufacturers of dynamic random access memory (DRAM), Hynix Semiconductor and Samsung Electronics, have demonstrated working DDR4 modules at the International Solid-State Circuits Conference (ISSCC). Interestingly, but other manufacturers of DRAM, refrained from showing off their DDR4 prototypes.

Samsung's DDR4 DRAM module can achieve data transfer rates of 2133Gb/s at 1.2V, compared to 1.35V and 1.5V DDR3 DRAM at an equivalent 30nm-class process technology, with speeds of up to 1.6Gb/s. When applied to a notebook, it reduces power consumption by 40% compared to a 1.5VDDR3 module.

At ISSCC 2012, both Samsung and Hynix demoed already announced DDR4 prototypes with 30nm and 38nm technology nodes, respectively, although mass production will begin later this year at 20nm, reports TechEye web-site. Elpida, Micron and Nanya reportedly did not show DDR4 prototypes at the show.

Hynix's DDR4 device works at 2400MHz (2400Mb/s) and operates at a low voltage of 1.2V and processes up to 19.2GB/s of data per second with a 64-bit I/O.

At present it is expected that DDR4 will be massively adopted by mid-2014, but manufacturers will likely start volume manufacturing of the next-gen DRAM sometimes in 2013.

Sweet, but what am I going to do with all the DDR3 I have invested in the past few years? The chasing game never end... and thankfully the excitement, too.

4GB of DDR3 can be had for $16 at my local PC store..

So its no great loss moving over to DDR4... the old stuff is next to worthless ayways

Keep it in the system it is now...DDR4 will only be supported by new platforms, so you will have already replaced the mobo/CPU so the RAM will be by far the cheapest thing to replace...

At this point DDR4 offers zero performance advantage over DDR3 - which is why no one is rushing DDR4 out-the-door.

My DDR2@1200Mhz smoke any DDR3 out there because of 5-5-5-15 timings. However, the power consumption is double of DDR3, and they also are getting red-hot. Performance is not everything...

why do we need to go up to DDR4 when this pc-100 stick still running fine with a 486dx2-66 running win95 and dual-boot Ubuntu. this old system cost me almost 4k years ago so it better work another decade or longer. my next system will be 5+ GHZ on air cooling or else I'll keep waiting until 2030 or when those TNG robots are available as home pet.

have fun running Ubuntu on your 486.

You have tech nonsense in your reports. 2133Gb/s should probably say 2133MT/s, and "2400MHz (2400Mb/s)" should probably be "2400MHz (2400MT/s)" to pull out 19200MBps on 64-bit bus and that the statement at least mathematically correct. Because otherwise pretty much resembles yellow journalism.
