from the SI breakdown and comments posted this AM....

 "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.

Now an update breakdown with comments by Protelligent.....

"The Samsung memory for the Samsung processor is a package-on-package construction and is Mobile DDR SDRAM, not SRAM as indicated [by SI]," said Carey."

 The difference...fwiw

"SRAM (static RAM) is random access memory (RAM) that retains data bits in its memory as long as power is being supplied. Unlike dynamic RAM (DRAM), which stores bits in cells consisting of a capacitor and a transistor, SRAM does not have to be periodically refreshed. Static RAM provides faster access to data and is more expensive than DRAM. SRAM is used for a computer's  cache memory"

 "SDRAM (synchronous DRAM) is a generic name for various kinds of dynamic random access memory (DRAM) that are synchronized with the clock speed that the microprocessor is optimized for."

===================================================

We have one company contradicting the other with regard to the RAM supplied...why do they each see things so differently?

 SRAM or DRAM?

When I read the SI report of  SRAM this AM...I saw it as a dual high speed caching scheme.....now it's being tossed as plain Jane SDRAM.

 Protelligent throwing a curve ball here?
