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

An operating method of a memory system, the operating method comprising:

• receiving a plurality of read requests from a host;
• determining whether to perform a correlation operation on the plurality of read requests based on the number of read requests;
• selectively performing the correlation operation on the plurality of read requests based on a result of the determining operation and transferring the correlated read requests to a plurality of memory dies through a plurality of channels;
• receiving data corresponding to the correlated read requests from the plurality of memory dies via the plurality of channels in an interleaving way;
• and
• outputting the received data to the host,
• wherein the correlated read requests include multiple read requests which are related to the same storage mode and different channels among the plurality of read requests.

A memory system comprising:

• a plurality of memory dies including multiple storage blocks;
• a controller;
• and
• a plurality of channels coupled between the controller and the plurality of memory dies,
• wherein the controller is suitable for:
• receiving a plurality of read requests from a host;
• determining whether to perform a correlation operation on at least some of the plurality of read requests based on the number of read requests and an order in which the read requests are received;
• when it is determined that the correlation operation is to be performed, performing the correlation operation on select read requests, among the plurality of read requests, to generate correlated read requests;
• and
• transferring the correlated read requests to the same storage block among the multiple storage blocks through different channels.
