Teardowns I've Worked On

Notes

  • iPad 3 4G Teardown

    As per this data sheet (http://omapworld.com/4430_8Gb__DDR_PoP_1...), each SDRAM chip has two 32-bit data channels, meaning that there is actually twice as much bandwidth as the iPad 2 / A5!

    Two chips, each with two 32-bit interfaces means the A5X has a 128-bit wide interface (backed up by the UBM die floorplan analysis). At 800MT/s (on a 400MHz clock), that corresponds to 12.8GB/s!
