Abstract:
Electronic systems, such as automobile radios, portable and other computing devices, and global positioning system receivers, often require that a correct security code be inputted from a small memory card that is removably inserted into a card slot of the system before the system is rendered operable in total or in part, or before certain data can be retrieved. The same type of memory card is also used to store digital data that is utilized by the system in conjunction with its function that is enabled by the security code, such data cards being removably inserted into the same card slot as the card containing the security code. Alternately, both the utilization data and the security code are included on a single card. An example application is an automobile radio wherein data supplied by the second card are of music that is reproduced through the radio's audio system.
Abstract:
A multiple die package for integrated circuits is disclosed. An insulator layer is provided and one or more vias are formed within it. The insulator may be provided without vias, and vias formed later. At least one integrated circuit is provided and electrically coupled to at least one lead of a first leadframe overlying one surface of the insulator layer. At least one second integrated circuit is provided and electrically coupled to a second leadframe overlying a second surface of the insulator layer. Electrical connections between the two leadframes and the first and second integrated circuits are made through the insulator, at selected locations, by coupling at least one lead of the first and second leadframes one to another. The leads of the first and second leadframe may be physically coupled by a welding process within vias in the insulator. A removable storage card package is also described.

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.
Abstract:
Very small non-volatile memory cards are modified to include a connector to which a connector on a separate data input-output card electrically and mechanically mates when pushed together. The input-output card transfers data directly between an external device and the non-volatile memory, without having to go through the host to which the memory card is connected. The input-output card communicates with the external device through a wired or a wireless communication channel.
