摘要： A Multi-Media Card/Secure Digital (MMC/SD) single-chip flash device contains a MMC/SD flash microcontroller and flash mass storage blocks containing flash memory arrays that are block-addressable rather than randomly-addressable. MMC/SD transactions from a host MMC/SD bus are read by a bus transceiver on the MMC/SD flash microcontroller. Various routines that execute on a CPU in the MMC/SD flash microcontroller are activated in response to commands in the MMC/SD transactions. A flash-memory controller in the MMC/SD flash microcontroller transfers data from the bus transceiver to the flash mass storage blocks for storage. Rather than boot from an internal ROM coupled to the CPU, a boot loader is transferred by DMA from the first page of the flash mass storage block to an internal RAM. The flash memory is automatically read from the first page at power-on. The CPU then executes the boot loader from the internal RAM to load the control program.
