  • Patent number: 7522424
    Abstract: A multi-memory media adapter comprised of a first planar element having an upper surface and a lower surface, a second planar element having an upper surface and a lower surface, and formed from a single material. The two planar elements form at least one port, each port capable of receiving one or more types of a memory media card. The adapter has at least one set of contact pins protruding from the lower surface of the first planar element or the upper surface of the second planar element such that the at least one set of contact pins are disposed within the port. The at least one set of contact pins are capable of contacting the contacts of a memory media card inserted into the port. For one embodiment a controller chip is embedded within the single material forming the multi-memory media adapter.

  • Publication number: 20090100207
    Abstract: A memory card reader is disclosed. In one embodiment, the memory card reader comprises a first slot to receive a first memory card of a first format; a second slot to receive a second memory card of a second format having fewer interface pins than the first format; an Integrated Device Electronics (IDE) interface for transferring data to a system; and a single IDE converter, coupled to the IDE interface and the first and second slot, to interface with a memory card of the first format inserted in the first slot or a memory card of the second format inserted in the second slot, to convert signals from the first or second memory card into a format for the IDE interface, and the converter to detect a card inserted in the first or second slot by detecting a voltage change in the first or second slot.

  • Patent number: 7493437
    Abstract: A single-slot multi-flash-card reader is disclosed. The flash-card reader includes an Integrated Device Electronics (IDE) interface for transferring data to a personal computer; and an IDE converter, coupled to the IDE interface, for converting multiple flash-card interfaces to a format used by the personal computer interface. The multiple flash-card interfaces include a COMPACTFLASH interface and smaller interfaces having fewer pins that the COMPACTFLASH interface. The flash-card reader includes a COMPACTFLASH connector, coupled to the IDE converter, for receiving a COMPACTFLASH card through a single slot in the single-slot multi-flash-card reader, the COMPACTFLASH connector making electrical connection with the COMPACTFLASH card for signals in the COMPACTFLASH interface. The flash-card reader also includes an adapter, having a physical shape to remove or insert into the COMPACTFLASH connector. The adapter has a mating COMPACTFLASH connector that fits the COMPACTFLASH connector.

  • Publication number: 20090043831
    Abstract: A method and apparatus for dynamically distributing data to an appropriate storage device based on the significance of the data. In one embodiment the method determines the significance of a data file using the format of the data file. The method also includes identifying a storage device and memory location of the storage device to write the data. In a software implementation, a computer system employs a filter driver and/or a device driver to identify and store data files. In another embodiment, a storage controller includes a state machine that initiates and executes firmware to determine the data file format and also the storage device location.

  • Publication number: 20080299809
    Abstract: A multi-memory media adapter having a port, a surface, and a set of contact pins adapted to connect to different types of flash cards. Signals are mapped to the contact pins depending upon the type of flash card. In one embodiment, a controller has signal lines connected to an interconnection means which connects wires, cables or traces to the sets of contact pins. Signals are mapped on the signal lines depending upon the type of flash card inserted.

  • Publication number: 20080250174
    Abstract: A flash-memory-card reader reads and writes multiple types of flash-memory cards, including CompactFlash, and the smaller SmartMedia, MultiMediaCard, Secure Digital, and Memory Stick. A converter chip converts the different card signals for transfer to a host personal computer (PC). Serial-to-parallel data conversion is performed for the smaller card formats with serial data interfaces, but not for CompactFlash with a parallel-data interface. A single slot has a 50-pin connector for CompactFlash cards or passive adapters. The passive adapters have the CompactFlash form factor and a smaller connector fitting smaller flash cards. Passive adapters have no components but simply wire the smaller connector to the CompactFlash connector. A pin mapping allows card-type detection by sensing the LSB address pins of the CompactFlash interface. A larger CompactFlash reader has multiple slots for each card type. The reader is connected to the PC by a cable, or located within the PC chassis in a drive bay.
