Mobile DRAM may become mainstream in smartphones in 2014

Mobile DRAM may become mainstream in smartphones in 2014
So far, the trend in mobile devices has simply been to put more and more RAM into devices. But, you knew that eventually manufacturers would move away from that trend a bit and move towards simply using better RAM. At least that's the theory coming from DRAMeXchange, which is claiming that 2014 will be the year of mobile DRAM.

So far, mobile devices have been using DRAM that is built and optimized for PCs, not mobile devices, meaning more power efficiency in mobile devices. Obviously, when designing hardware components for PCs, there isn't as much of a worry about power efficiency, because PCs are always plugged in, but power is always a big consideration in mobile. 

The expectation is that LPDDR3 will replace LPDDR2 as the mainstream product in mobile devices, which will be great for users because LPDDR3 drops the power usage of the RAM from 2.5V to 1.8V. Looking even farther down the road, LPDDR4 is expected to see limited release in 2015, and become the mainstream option in 2016.

Lets add removable batteries, removable storage and now removable ram to all phones in 2014 and beyond!

Indeed great news! I mean for all us non iClones, as Apple will never do any of that , ever, LIKE EVAR! hahahaha!

Yep.. That stuff would be nice❕❕
Nevertheless, I don't hate on Apple.. How would I look hating on Apple when I don't like people hating on WP❔.. All three platforms serve their purpose, rightfully..

Ahem... sir,

may I remind you that the RAM is stacked on the chip and packed?

That's what SoC(System on Chip) is all about : CPU, "mainboard" and RAM in a single chip.

It's of course possible to make the RAM removable, it would just take as much space as the battery in addition to consuming more than four times the power. - off the table.

Both removable battery and storage also have their drawbacks :
- losses in space.
- since the battery/storage can be removed ANYTIME, the OS always has to do even the smallest storage transactions immediately instead of scheduling them to be more efficient. This consumes more cycles and power the whole time.
- Removable storages are generally much slower.
- Their are tons of compatibility issues with all those microSDs, and the OEM has to do lots of extra work with their drivers, thus increasing the manufacturing cost.

There are reasons why Google didn't make anything removable on the N4/5.

Nah, the RAM is not stacked on the CPU. SoC contains CPU, GPU, GPS, networking hardware, & etc.
RAM is still separated from SoC, but soldered to motherboard

Oops, you are right. I was speaking from old days a few years ago. Nowdays, the DRAM is soldered on the board and only the SRAM reside in the chip.

i never wanted removable battery. most people can recharge their phone when they arrive home from work. most phones shouldn't have removable battery.

can i also have "removable" or "customizable" screen, camera lens, graphic chip, speakers etc?

you have to wait 5 years to see Lumia using this technology

Really❔.. It didn't take long for Nokia to move to Dual core, Quad core, and 1gb-2gb of ram.. If WP has to wait so long then why is there a WP device, that's on the market right now, with what may be some of the best specks available on any device❔.... You can keep trying to hate on WP, but find some new material, because the things you use are old arguments that aren't valid anymore... You sound pathetic.

Indeed a great news .. I believe this a progress in right direction than just increasing the RAM size .. Manufacturers shall adopt this asap.

Well, DDR3 is already mainstream in high end devices.
They get over 10Gb/S memory bandwidth, and about 90-100 Mb/s read speed.
Snapdragon 805 will more than double that with 25Gb/s bandwidth and over 200MB/ random read
