1. A memory system, comprising:
a memory device including plural storage regions including plural non-volatile memory cells and having a different data input/output speed; and
a controller coupled to the memory device via at least one data path and configured to:
perform a readahead operation in response to a read request input from an external device,
determine a data attribute regarding readahead data stored in a buffer, included in the controller, through the readahead operation, based on a time difference between reception of the read request and completion of the readahead operation, and
store the readahead data in one of the plural storage regions based on the data attribute.
