The A8 was definitely manufactured by TSMC in TAIWAN!~

The part no. of SDRAM (F8164A3PM-GD-F) can be found on the right of Apple A8 SOC.

According to the datasheet, F is the product family (Mobile LPDDR3 SDRAM); A is the power supply interface (1.8V and 1.2V); 3 is the revision; PM is the package code.

This SDRAM should be a customized product with customized package (the SDRAM in Apple A7 SOC is F8164A1PD while the standard part no. is F8164A1MA).

'8' stands for 8Gb=1GB (for 2GB SDRAM, the part no. will be 'A')

"64" stands for 64-bit data width (for 32-bit SDRAM, the part no. will be "32")
