Abstract
A memory card including a PCB assembly that is consistent with existing 13-pad MMC mechanical form factors, and a housing that is consistent with the SD mechanical form factor, thereby providing a single PCBA and housing arrangement that can be used to produce both MMC and SD memory cards. The thirteen contact pads support all MMC and SD contact pad patterns, but are modified to facilitate a write protect switch. The housing includes an enlarged window (or windows) that exposes two or more contact pads in each of the multiple rows, thereby facilitating slidable insertion of the memory card into a socket of a host system. Alignment notches are formed in the side edges of the PCB, and/or alignment pins are utilized for properly aligning the PCBA within the housing.
