Memory card pad layout supporting multiple communication protocols

摘要

Memory cards having a nano card form factor configured according to different card standards. The nano card have a pair of opposed surfaces having a length and width of a nano SIM card in which a first group of interface pads on one of the opposed surfaces configured to mate with contact pins of a host device card slot operating per a PCIe memory card standard and a second group of interface pads configured to mate with contact pins of a host device card slot operating per a second memory card standard different than the PCIe memory card standard. The nano cards have patterns of pads allowing for vertical and horizontal insertion to a host device card slot being backward compatible with legacy host device card slots.
