Claim 17:
18. A storage controller, comprising:
an on-chip valley search (OVS) management module configured to generate an OVS read request for a memory region of a non-volatile memory device;
a command generator configured to generate a first command including the OVS read request of the memory region and a second command including a request for OVS count data, under control of the OVS management module;
a non-volatile memory interface circuit configured to provide the first and second commands to the non-volatile memory device, and to receive the OVS count data from the non-volatile memory device; and
a type determiner configured to determine a distribution type of the memory region to be a predicted distribution type, from among a plurality of distribution types, based on the OVS count data.
