ABSTRACT:
A data copy method includes designating data stored in a non-volatile memory device as data packages, reading at least one data package to store the read at least one data package in a temporary memory device, transferring the at least one data package stored in the temporary memory device to a volatile memory device using a direct memory access (DMA) operation, and reading a next at least one data package stored in the non-volatile memory device to store the next at least one data package in the temporary memory device. Transferring the at least one data package and reading the next at least one data package are simultaneously and parallelly performed. The data copy method according to exemplary embodiments of the present invention may improve data copy speed, and may reduce occupancy of a memory bus by performing the auto-loading function and simultaneously and parallelly performing the data package storing process and the data package transferring process.
