Abstract
A data transfer method and system are provided that prevent the length of a time required for writing to a flash memory from appearing on the surface as a system operation when the flash memory is used in place of an SRAM. The method of transferring data includes the steps of writing data from a controller to a volatile memory, placing the volatile memory in a transfer state, transferring the data from the volatile memory in the transfer state to a nonvolatile memory, and releasing the volatile memory from the transfer state in response to confirming completion of the transfer of the data.
