Samsung unveils ePoP phone memory stack: 3GB RAM and 32GB storage now take 40% less space

Samsung unveils ePoP phone memory stack: 3GB RAM and 32GB storage now take 40% less space
Samsung just announced a breakthrough in phone memory packaging, which fuses 3 GB of RAM and 32 GB of storage in a single small package, allowing the kit to occupy 40% less space in our smartphones than a similar setup does now. This will leave more space for a battery pack in slim handsets, or whatever the engineering teams decide to do with the free air left inside.

The brainiacs from Samsung have already started mass producing the industry’s first ePoP (embedded package on package) chip, which is a marked improvement over the current two-package eMCP memory solutions. The 3GB LPDDR3 mobile DRAM utilized runs at an I/O data transfer rate of 1,866 Mb/s, and comes with a 64-bit bandwidth. 

The ePoP packaging occupies exactly the 225 square millimeters space that a conventional mobile CPU takes, and is just 1.4mm thin, so it can be stacked on top of it, unlike current two-package editions that take 374.5 square millimeters. “By offering our new high-density ePoP memory for flagship smartphones, Samsung expects to provide its customers with significant design benefits, while enabling faster and longer operation of multi-tasking features,” Jeeho Baek, Senior Vice President of Memory Marketing at Samsung Electronics. “We plan to expand our line-up of ePoP memory with packages involving enhancements in performance and density over the next few years, to further add to the growth of premium mobile market.” There you have it.

Only if it were 4GB LPDDR4 + 64 GB instead of 3GB LPDDR3 + 32 GB, then it would have struck the right point!!!

Seems oriented towards premium midrangers (no LPDDR4 RAM to sweeten the package). This is still dang impressive. Kudos!

Yes, but once you know how to do it, it won't be that difficult to improve the innards.

Only 32GB and not 64GB? Only 3GB of LPDDR3 and not 4GB DPDDR4? Boo... hiss!!! Sounds like mid-range specs for 2015.

Its just been created, once they have this stable they can begin working on storage amount and speed, so this is a very nice step forward :)

surprised at the lack of DDR4 in a package that would only be in high end device

It's a new tech, LPDDR4 is also just being mass produced. Obviously integration will take a bit of time. Key here is to know how to integrate them. They can obviously work on LPDDR4 once they become mainstream. And I believe this is aimed at other smaller vendors who wants to buy a ready-made solution without the need to implement separate components.

Turely innovative. But i don't think flagship phone going to use it as most of the report pointed out that in 2015 most flagship andorid phones going to use DD4 ram, i don't believe that they're going to stick with DD3 ram (DDR3 is still very good).

But we'll stick with 16gb of storage on our flagship phones. It's more than enough for everyone's needs. We did provide a microSD card slot, for your convenience.
