"The first Apple branded component is the Samsung processor, which is a three stacked die package containing an S5L8900 and two 512 Mbit SRAM dice," said Quirk. While SI has not seen the S5L8900 marking before, it said the numbering conforms to other Samsung processors found in smart phones and PDAs.

Samsung's 65-nm 8-Gbyte MLC NAND flash (K9MCG08U5M) was used in the iPhone. "This is the exact same component that was used in the 8-Gbyte iPod nano," said Quirk. "This memory is used to store things like songs, pictures, and videos. Samsung provides the K9HBG08U1M in the 4-Gbyte version of the iPhone."

"The iPhone also implements Intel wireless flash with 32 Mbytes of NOR coupled with 16 Mbytes of SRAM for code execution. "Interestingly, many in the industry predicted a design win for Intel, but thought it would be for an Intel (now Marvell) applications processor instead of flash memory," said Quirk."

IMO...utilizing two 512 Mbit SRAM could be a hint. One would have to find out if the two units function in an advance streaming of read and write to and from the primary memory (Samsung's 65-nm 8-Gbyte MLC NAND flash). If so, IMO, this would be similar to the advanced caching manor of e.Digital, as opposed to the normally shadowing NAND to RAM.
