摘要： An electronic data flash card is accessible by a host computer, and includes a processing unit connected to a flash memory device that stores a data file, and an input-output interface circuit activated so as to establish a communication with the host computer. In an embodiment, the electronic data flash card uses a USB input/output interface circuit for communication with the host computer. A flash memory controller includes an index for converting logical addresses sent by the host computer into physical addresses associated with sectors of the flash memory device. The index is controlled by arbitration logic referencing to values from various look up tables and valid data stored in the flash memory device. The flash memory controller further includes a first-in-first-out unit (FIFO) for recycling obsolete sectors of the flash memory device in the background process so that they are available for reprogramming.

摘要： A flash microcontroller has a Static Random-Access-Memory (SRAM) buffer that stores several blocks of boot code read from a flash memory. The SRAM buffer also operates as a cache of flash data after booting is complete. Cache read and write hits use the SRAM cache rather than flash memory, while old cache lines and read misses access the flash memory. Both the external host and the microcontroller are booted from boot code buffered in the SRAM buffer. A boot-loader state machine reads the flash ID and programs flash parameter registers with timing parameters for the flash memory. The flash microcontroller uses a differential interface to the external host, with a differential transceiver and a differential serial interface. Frame, packet, and encoded clock processing is also performed by the serial interface.
