Samsung Cranks Up LPDDR4 Memory for Mobile Devices

Does mobile really need it? Yes and no.

The Korean Times reports Samsung Electronics has started mass production of the first first 8-gigabit, low power double data rate 4 (LPDDR4) DRAM for mobile devices, which will be made using 20 nanometer processing technology.

This is actually a good development, though, because DDR4 does have one advantage for mobile users: lower power consumption.

DDR4 is hitting the market now and will really start to come to bear next year. It has two major changes over DDR3. First is lower power draw. DDR3 consumes 1.5 volts of power, while DDR4 is 1.2 volts, a 20 percent reduction.

The other change is its speed. DDR3 tops out at around 2,133Mhz speed, while DDR4 will go to 3,200 Mhz and possibly higher. For mobile devices, this is irrelevant. The only place this will prove beneficial is in servers, and Samsung is already making DDR4 for servers, as is every other memory maker.

In the case of LPDDR4, the power draw is even lower: 1.1 volts. This can only help improve battery life in mobile devices. Samsung is claiming the LPDDR4 will use 40 percent less power than the DDR3 it has been using. That will definitely have an impact on battery life.

We'll see if they can put their money where their mouth is, because the new Samsung memory will be used in the company's new Galaxy S6 phone. There has been plenty of rumor and speculation on the S6, but the truth is it's months away. Then again, it may get previewed at CES next week.

The big question is whether this memory will find its way into the iPhone 7. Given the up and down nature of the Apple/Samsung relationship, I won't even try to speculate on that possibility.
