Claim 9:
10. An operating method of a storage controller which communicates with a host and a plurality of flash memory regions, the method comprising:
monitoring the plurality of flash memory regions;
updating a status information set based on the monitoring, wherein the status information set includes a plurality of status information respectively corresponding to the plurality of flash memory regions;
determining whether the plurality of flash memory regions are available, based on the updated status information set;
generating monitoring information indicating that a first flash memory region of the plurality of flash memory regions is unavailable, based on a result of the determination; and
outputting the monitoring information to the host
wherein the monitoring of the plurality of flash memory regions includes:
periodically determining whether each of the flash memory regions satisfies an available memory condition, every reference time,
wherein the available memory condition is a condition where a value obtained by subtracting a minimum value of a plurality of average erase counts of the plurality of flash memory regions from an average erase count of a corresponding flash memory region is smaller than a first threshold value.
