Abstract
A mother/daughter card non-volatile memory system includes a daughter card containing the memory and a mother card containing the memory controller and host interface circuits. The daughter memory card contains as little more than the memory cell array as is practical, in order to minimize its cost, and has an interface for connecting with a variety of mother controller cards having physical attributes and host interfaces according to a number of different published or proprietary memory card standards. Different types of memory cards may be used when the operating parameters of the memory are stored within it in a protected location, the mother card controller then reading these parameters and adapting its operation accordingly. A radio frequency antenna may be included on a surface of the card along with its electrical contacts, in order to provide a radio frequency identification function.
