  • Patent number: 6246578
    Abstract: A computer-dedicated auxiliary data access device comprised of a device case having a minimum of one horizontal slot in the front side and, furthermore, a housing cavity perpendicularly formed inward beyond the horizontal slot, a universal serial bus interface socket installed at the end section of the housing cavity, an IC circuit board disposed in parallel alignment with the horizontal slot, a card terminal connector respectively situated at the end face of the IC circuit board, and a number of perpendicularly supportive spring contacts of the card terminal connector that are connected via a flat cable routed to the interface socket. The horizontal slot provides for the sideways insertion of an ultra thin flat memory card, with the memory card internally consisting of high-speed flash memory chips and also including a main controller IC and a memory IC which have a read/write specification of 10,000 times to enable the rapid reading and writing of data.
