    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: A data storage device includes one or more electrical contacts and one or more data paths through the electrical contacts. The one or more electrical contacts enable bits to be transferred into and out of the data storage device via the one or more data paths. The data storage device also includes a memory that stores an indication of a number of the one or more data paths. The data storage device is configured to provide the indication via at least one of the one or more data paths while the data storage device is operatively coupled to a host device to indicate to the host device the number of the one or more data paths.

    摘要: A removable data storage device that intelligently operates as one large data storage region or as multiple, smaller data storage regions is disclosed. The removable data storage device can be used in not only modern electronic products (using 32-bit addressing) but also legacy products (using 16-bit addressing). A host device can couple to the removable storage device to access data stored in/to the removable storage device. As an example, the removable data storage device can be a memory card.

    摘要: A programmable controller includes an interface circuit for communicating with a host CPU. The interface circuit includes a FIFO memory having a plurality of locations, each location receiving address and data information. The data information can either be an operand or a command. Whether the data information is an operand or a command is determined by one of the bits of the address. If the data information is an operand, it is stored at a location determined by the address. Accordingly, in a single host CPU cycle, the host CPU can write one word to the controller which comprises either a command or data and the address where the data can be stored. Multiple cycles are not required to provide a single instruction or data to the controller. Further, because a FIFO memory is used, a plurality of instructions are loaded into the controller and the controller and the host CPU can operate asynchronously. The controller also includes an EPROM for providing instructions to an internal CPU and a sequencer for providing addresses to the EPROM. The EPROM provides an output word including a bit field containing instructions for the sequencer, a bit field containing instructions for the CPU, and a bit field including instructions which are sent directly to the peripheral device. Accordingly, the controller can perform a plurality of instructions in parallel.

    摘要: The present invention allows for an increase in programming parallelism in a non-volatile memory system without incurring additional data transfer latency. Data is transferred from a controller to a first memory chip and a programming operation is caused to begin. While that first memory chip is busy performing that program operation, data is transferred from the controller to a second memory chip and a programming operation is caused to begin in that chip. Data transfer can begin to the first memory chip again once it has completed its programming operation even though the second chip is still busy performing its program operation. In this manner high parallelism of programming operation is achieved without incurring the latency cost of performing the additional data transfers. Two sets of embodiments are presented, one that preserves the host data in a buffer until successful programming of that data is confirmed and one that does not require that success be achieved and that does not preserve the data thus achieving a higher rate of data programming throughput.

    摘要: In a memory array having redundant columns, a scheme allows defective cells to be individually remapped to redundant cells in a redundant column. Redundant cells in one redundant column replace defective cells in multiple non-redundant columns. Remapping is done as part of initial test and configuration. Specific hardware can be used for the scheme or firmware in the memory controller can implement the scheme.
