Modern application processors for smartphones need 225mm² (15*15mm) of space. A conventional PoP, consisting of the AP and DRAM, along with a separate eMMC (11.5mm*13mm) NAND flash package, takes up to 374.5mm². Replacing that set-up with a Samsung ePoP decreases the total area used by approximately 40 per cent to 225mm². As a result, it is possible to install more components or a larger battery into a smartphone. Previously Samsung offered ePoP for various wearable electronics devices.
