Apple iPhone 6S: LPDDR4 arrives at Apple

As reported by Chipworks last week, the Apple iPhone 6S is using 2GB of LPDDR4 DRAM. This means that Apple is now joining other phones such as the LG Gflex2, the Samsung Galaxy S6, Xiaomi Mi Note Pro, HTC OneM9, and several others in using LPDDR4 RAM.

Zero to Green Light in minutes: Prototype your DDR Designs faster with new DDR IP Prototyping Kit

I’m thrilled to blog about our latest IP prototyping kits that allow much faster FPGA prototyping of your DDR designs. In the last few years I’ve seen our HAPS prototyping boxes at more and more of our customers, and people I’ve talked to really like the ability to do their software prototyping for their DDR IP on their desktops long before their SoCs are manufactured.

The Future of DRAM

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.

Happy 10th Birthday DDR4!

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?

When is LPDDR3 not LPDDR3? When it’s DDR3L…

For years, I have been predicting that Low-Power DDR (LPDDR) devices would make the crossover from mobile devices into laptops.

Could mobile DRAM exceed PC DRAM shipments in 2014?

Mobile DRAM has certainly come a long way in the last few years, but I didn’t expect to see this prediction quite so soon, that “…the shipment of mobile DRAM is likely to officially surpass that of PC DRAM in 2014”.
