As predicted in my earlier blog entry, today is the official launch of Intel’s products supporting DDR4.
Following today’s event in Seoul, there are still two more JEDEC LPDDR4 Workshops and Mobile Forums coming up in the next few weeks.
There is a ton of internet speculation today – mostly based on a report on a Japanese website – that Intel will make it’s first DDR4-compatible products available on August 29th and that internet retailers may make those products available for sale the same day. Earlier speculation was that Intel would release the DDR4-compatible products in time for the Intel Developer Forum in mid-September.
A lot has been written about DDR SDRAMs, both the compute variety (DDR3/4) and the mobile variety (LPDDR3/4) and what may come after these technologies run their course. One thing is certain; the future will not be an easy path for DRAMs. The DDR protocol based on a wide parallel bus with single ended signaling and a source synchronous data strobe and non-embedded clock is not scalable beyond the data rates currently specified for these technologies. After DDR4, the world will need something else as the DDR interface cannot realistically be expected to run at data rates higher than 3200Mbps in a traditional computer main memory environment. Unfortunately, that something else will likely be “somethings” else. Likewise, the smartphone’s insatiable need for higher bandwidth from main memory DRAM will also lead to a deviation from the wide parallel bus based DRAM.
We are thrilled about today’s blog topic: the announcement of Synopsys’s complete LPDDR4 IP solution!
This is a big day for DDR4: For the first time, Intel has announced DDR4 support in their desktop CPU roadmap.
I think I have found the first DDR4 DIMMs available for consumer purchase anywhere. Crucial and a few others were showing DDR4 DIMMs at this year’s Consumer Electronics Show (CES) in January, so it’s nice to see that they translated into real products.
Believe it or not, work the DDR4 standard was first started back in 2004. That’s now 10 years ago! Happy 10th birthday DDR4. 10 years ago Facebook was started up, there was no Twitter (2006), no iPhone (2007), and Google went public for $85/share (it is now $1,123/share). Even after those 10 years, you can’t go out a buy a computer with DDR4 in it. The JEDEC standard for DDR4 was published in September 2012 so why isn’t everyone using it? Why did it take so long?
For years, I have been predicting that Low-Power DDR (LPDDR) devices would make the crossover from mobile devices into laptops.
Happy New Year to all our blog readers!
