    Abstract: 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.

    Abstract: A secure memory card with encryption capabilities comprises various life cycle states that allow for testing of the hardware and software of the card in certain of the states. The testing mechanisms are disabled in certain other of the states thus closing potential back doors to secure data and cryptographic keys. Controlled availability and generation of the keys required for encryption and decryption of data is such that even if back doors are accessed that previously encrypted data is impossible to decrypt and thus worthless even if a back door is found and maliciously pried open.

    Abstract: A device with mass storage capability that uses a readily available non secure memory for the mass storage but has firmware (and hardware) that provides security against unauthorized copying of data. This is true even though the firmware itself is stored in the non secure mass storage memory, and therefore potentially vulnerable to hacking. An indication of the authenticity of the firmware must be present before it will be executed by the device. This protects the device contents from unauthorized duplication or tampering. Additional functionality can be added to the device with additional firmware applications, and the authenticity of those additional applications will also be verified before they will be executed. This further prevents unauthorized copying or tampering of secure content through any mechanisms that may be unscrupulously introduced. Any data within the mass storage memory may also be encrypted.

    Abstract: 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.

    Abstract: In a non-volatile memory system, test data may be retrieved by means of a circuit without the help of firmware. The circuit is triggered into action when it detects an abnormality in the processor or host interface. In such event, it formats the self test or status signals from the various blocks in the non-volatile memory system controller and sends a test message to the outside world without the assistance of the system processor or interface controller. When implemented in memory systems with multiple data lines, only one of the data lines may be utilized for such purpose, thereby allowing the testing to be performed while the system is still performing data transfer. Preferably, the system includes the test mode communication controller, which can select between a test channel and a host interface channel for the test message transfer so that the same testing may be performed when the memory system is in the test package as well as in an encapsulated package. The test message is transmitted repeatedly and the test message is structured so that it is easier for the receiver host to decipher the message without a handshake with the memory system. A communication controller preferably detects whether any of the communication channels is not used by the controller of a non-volatile memory system for sending signals and sends diagnostic signals through such channel.
