A memory system applied to an electronic device has a small-capacity linear-addressed nonvolatile memory having a boot code and system information stored therein and a high-capacity data flash memory in which an operating system (OS) and frequently accessed user data are recorded. While the memory system is booting up, the boot code including the system information is fetched from the linear-addressed nonvolatile memory to start an initialization process. After completion of the initialization process, the OS is retrieved from the data flash memory and executed. During the OS retrieval, the memory system provides an ECC/EDC unit to detect whether any bit error occurs and to correct any if present. Since the boot code and OS are stored in different memories, the bit error rate (BER) is effectively reduced.
