I'm curious how much RAM it has but it seems no one knows yet even after a teardown.

- petercooper 17y agoThe teardown indicates that "K4X2" is written on the A4 chip and they believe this to be a Samsung DRAM part number. I Googled for it but found nothing helpful so am going to stab in the dark and guess 4 gigabits (a more common measurement on-the-chip for memory) * 2 == 512MB * 2 == 1 gigabyte. Of course, that's a total guess and I've not seen memory part numbers work quite that way before ;-)
- tienshiao 17y agoFrom Step 15 (http://www.ifixit.com/Teardown/iPad-Teardown/2183/2 http://www.ifixit.com/Teardown/iPad-Teardown/2183/2): Markings on the A4: - N26CGM0T 1007 APL0398 33950084 YNL184A2 1004 K4X2G643GE - Yes, the K4X2 is a Samsung DRAM part number! - Decoding the part number shows there is 2Gb of memory inside. This translates into ~256MB of memory. - This means the A4 processor is probably being manufactured by Samsung. - The DRAM was stamped at the end of January, while the processor die was likely manufactured the third week of February.
