Apple A6 SoC 'confirmed' to leverage 1GB of RAMSlides of Apple's A6 chip presented at the company's iPhone 5 debut event on Wednesday reveal the processor likely holds 1GB of RAM, double the amount found in the legacy iPhone 4 and 4S handsets.
As noted by AnandTech, the unobscured parts numbers seen on the chip point to a Samsung DRAM component which boasts 1GB of addressable RAM.

The part number emblazoned on the A6 is K3PE7E700F-XGC2 which, according to Samsung's 2012 product guide is a package-stacked DRAM module. This is in line with Apple's A-series SoCs, which implement a package-on-package design to save space.
Breaking down the part number, "K3P" points to a dual-channel LPDDR2 package with 32-bit channels, while the "E7E7" designation denotes the 512MB density of each DRAM die, which comes out to a total of 1GB of RAM. Finally, the "C2" yields the part's 1066MHz cycle time/data rate.
The publication notes the new package should give the A6 a 33 percent boost in peak memory bandwidth compared to the iPhone 4S.
It was recently speculated that the new A6 processor could hold the company's first custom-designed CPU core, a departure from previous A-series SoCs which relied solely on ARM's patented technology.
