    摘要: An electronic device includes a universal serial bus (USB) interface therein. This USB interface is configured to support at least first and second different USB interface standards. These different interface standards are selected by the electronic device in response to comparing a voltage level of a signal provided to said USB interface relative to a reference voltage generated within the electronic device. The signal provided to the USB may be a power supply signal, the first USB standard may be a USB 2.0 interface standard and the second USB standard may be an inter-chip USB interface standard.

    摘要: An encryption processor, for storing encrypted data in a memory chip of a memory card, includes a FIFO memory for sequentially outputting m-bit data in response to a first signal, and an encryption key generator for generating m-bit encrypted keys (m being a positive integer) in response to a second signal and for sequentially outputting the keys in response to a third signal. A logic operator performs a logic operation on the data from the FIFO memory with the keys from the encryption key generator during a data write operation to sequentially encrypt the data. The logic operator performs a logic operation on the encrypted data received from a memory interface with the keys output from the encryption key generator during a data read operation in order to sequentially decode the encrypted data. The second signal is simultaneously generated with one of the write command or the read command.

    摘要: A method and apparatus for resetting a memory card having a plurality of interfaces and a plurality of function blocks, wherein each function block may be associated with a corresponding interface, may include detecting a reset signal for a selected interface of the plurality of interfaces, and interrupting a function block associated with the selected interface. When the selected interface is the only active interface, all function blocks in the memory card may be reset. If interfaces other than the selected interface are active, only the selected interface may be reset.
