    摘要: A memory card of one published standard, such as the Multi-Media Card (MMC) or Secure Digital Card (SD), is modified to include the function of a Subscriber Identity Module (SIM) according to another published standard. The controller of the memory card communicates between electrical contacts on the outside of the card and both the memory and the SIM. In one specific form, the memory card has the physical configuration of the current Plug-in SIM card with a few external contacts added to accommodate the memory controller and data memory. In another specific form, the memory card has the physical configuration of the current SD card, including external contacts.

    摘要: Two or more very small encapsulated electronic circuit cards to which data are read and written are removably inserted into two or more sockets of a host system that is wired to the sockets. According to one aspect of the disclosure, command and response signals are normally communicated between the host and the cards by a single circuit commonly connected between the host and all of the sockets but during initialization of the system a unique relative card address is confirmed to have been written into each card inserted into the sockets by connecting the command and status circuit to each socket one at a time in sequence. This is a fast and relatively simple way of setting card addresses upon initialization of such a system. According to a second aspect of the disclosure, the host adapts to transferring data between it and different cards of the system over at least two different number of the data lines commonly connected between the host and all of one or more sockets, each card permanently storing a host readable indication of the number of parallel data lines the card is capable of using. This allows increasing the rate of data transfer when the need justifies an increased card circuit complexity. According to a third aspect of the disclosure, a serial stream of data is sent over a number of data lines from one to many by alternately connecting bits of the stream to a particular number of individual lines.

    摘要: A removable electronic circuit card having both a memory module with a non-volatile mass storage memory and a separate input-output module so that data transfers may be made through the input-output module directly to and from the mass storage memory in a direct memory access (DMA) type transfer when the card is inserted into the host system but without having to pass the data through the host system. Once the host gives a DMA command, the data transfer is accomplished independently of the host system, except for the host supplying power and possibly a clock signal and other like support, during such a data transfer directly with card. The data for the transfer can be communicated between the input-output module and the exterior device through either wireless or an electrical connection means.

    摘要: A method of transmitting a stream of data bits from a memory card to a host device includes determining, at the memory card, a first number of data lines between the memory card and the host device, from one to a plurality of data lines. If the first number of data lines is determined to be a plurality of data lines, the method includes switching, at the memory card, the data stream between one of the first number of data lines and another of the first number of data lines after each occurrence of a second number of one or more bits of the data stream having passed toward the host device. The method also includes, if the first number of data lines is determined to be one data line, transmitting, from the memory card, the stream of data bits over the one data line to the host device.
