"Slides 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. \r\n\r\nAs noted by &amp;lt;em&amp;gt;AnandTech&amp;lt;/em&amp;gt;, the &amp;lt;a href=\"http://www.anandtech.com/show/6297/iphone-5-memory-size-and-speed-revealed-1gb-lpddr21066\"&amp;gt;unobscured parts&amp;lt;/a&amp;gt; numbers seen on the chip point to a Samsung DRAM component which boasts 1GB of addressable RAM. \r\n\r\n&amp;lt;div align=\"center\"&amp;gt;&amp;lt;img src=\"http://photos.appleinsider.com/12.09.15-A6Mem.jpg\" alt=\"A6 Memory\" width=\"419\" height=\"450\" border=\"0\"&amp;gt;&amp;lt;br&amp;gt;&amp;lt;span class=\"minor2 small gray\"&amp;gt;Apple's A6 processor with Samsung DRAM package part number highlighted. | Source: &amp;lt;a href=\"http://www.apple.com\"&amp;gt;Apple&amp;lt;/a&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;/div&amp;gt;\r\n\r\nThe 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. \r\n\r\nBreaking 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.\r\n\r\nThe publication notes the new package should give the A6 a 33 percent boost in peak memory bandwidth compared to the iPhone 4S.\r\n\r\nIt 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."^^<http://www.w3.org/2001/XMLSchema#string>
