Personal Computer Memory Card International Association: a consortium of computer manufacturers that devised the standard for the credit card-size adapter cards used in many notebook computers. PCMCIA defines three card types: Type I cards can be up to 3.3mm thick and are generally used for RAM and ROM expansion cards; Type II cards can be as thick as 5.5mm and typically house modems and fax modems; Type III cards are the largest of the lot (up to 10.5mm thick) and are mostly used for solid state disks or miniature hard disks. PCMCIA cards are also known as “PC Cards”.
