  • Multiprocessor system having an input/output (I/O) bridge circuit for transferring data between volatile and non-volatile memory
    Patent number: 8060708
    Abstract: A disclosed circuit includes circuitry for coupling to a volatile memory, circuitry for coupling to a nonvolatile NAND flash memory, and circuitry that: (i) receives a volatile memory request from a processor and satisfies the volatile memory request by accessing the volatile memory, and (ii) receives a nonvolatile NOR flash memory read request from the processor and satisfies the NOR read request by accessing both the NAND flash memory and the volatile memory. The circuit may also include circuitry that receives a volatile memory request from another processor and satisfies the volatile memory request from the other processor by accessing the volatile memory, and circuitry that receives a NAND flash memory read request from the other processor and satisfies the NAND read request by accessing the NAND flash memory. Multiprocessor systems including the circuit are described, as is a method for satisfying a NOR flash memory read request.
