The 254-ball layout is meticulously split into functional zones: high-speed differential signal pairs, power rails, ground shielding, and control/test pins.
A standard UFS BGA 254 IC integrates two main components into a single silicon package: a 3D NAND flash memory array and an intelligent UFS controller. The physical dimensions typically measure 11.5mm x 13.0mm with varying thicknesses (often 1.0mm or less) depending on the storage capacity. The 254-ball layout provides dedicated paths for high-speed differential signaling lines, robust power distribution networks, and ground isolation to prevent electromagnetic interference (EMI).
