1. A memory system comprising:
- a memory device comprising a plurality of memory dies, each memory die being suitable for performing one or more corresponding command operations in response to a plurality of corresponding commands received from a host operatively coupled to the memory system; and
a controller suitable for issuing read status (RS) commands to the memory dies included in a first memory die group defined among the memory dies, issuing RS commands to the memory dies included in a second memory die group defined among the memory dies, checking whether the command operations are completed in the memory dies of the first and second memory die groups through responses to the RS commands, and respectively resetting issue periods of the RS commands according to the completion of the command operations of the memory dies of the first and second memory die groups.

Abstract
A memory system includes: a memory device comprising a plurality of memory dies in which command operations corresponding to a plurality of commands received from a host are performed; and a controller suitable for issuing RS (Read Status) commands to memory dies included in a first memory die group among the memory dies, issuing the RS commands to memory dies included in a second memory die group, checking whether the command operations are performed in the memory dies, through responses to the RS commands, and resetting an issue period of the RS commands in response to a change of the memory dies to which the RS commands are issued.

12. An operating method of a memory system comprising a memory device having a plurality of memory dies, the operating method comprising:
-
receiving a plurality of commands from a host for the memory dies, respectively; performing, by the respective memory dies, command operations in response to the commands; issuing read status (RS) commands to the memory dies included in a first memory die group; issuing the RS commands to the memory dies included in a second memory die group; checking whether the command operations are completed in the memory dies through responses to the RS commands; and respectively resetting issue periods of the RS commands according to the completion of the command operations of the memory dies. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
