Apparatus and method for improving input/output throughput of memory system

Abstract

A memory system includes: a plurality of memory dies, and a controller selects a second read request, including at least a portion of a plurality of first read requests, so that the memory dies interleave and output data corresponding to the first read requests, and performs a correlation operation for the selected second read request, when the second read request is selected, the controller determines whether the correlation operation is performed or not before a time at which the second read request is selected, determines whether the correlation operation is successful or not, determines a pending credit in response to an operation state of the memory dies at the time at which the second read request is selected, and determines whether to perform the correlation operation or not for the second read request that is selected at the time at which the second read request is selected based on the pending credit.
