Storage device and operating method thereof

A memory controller for controlling a memory device,

• wherein the memory controller is in communication with a host to receive one or more requests from the host and configured to enter a standby mode in case that a standby entry time has been expired, and the memory controller comprises:
• a temperature sensor configured to sense an internal temperature of the memory controller;
• an operation mode controller configured to adjust the standby entry time based on the internal temperature, and determine an operation mode based on the adjusted standby entry time and a host idle interval that is defined as an interval between host busy periods;
• and
• an operation controller configured to control the memory device according to the operation mode;
• wherein each of the host busy periods is a period between when a corresponding request is received from the host and when a response to the corresponding request is provided to the host.

A memory controller for controlling a memory device,

• wherein the memory controller is in communication with a host to receive one or more requests from the host and configured to operate in a standby mode based on a condition related to a standby entry time, and the memory controller comprises:
• an operation mode controller configured to adjust the standby entry time based on previous host idle intervals that occur before a current host idle interval, each previous host idle interval defined as an interval between host busy periods and each host busy period defined as an interval between a reception of a corresponding request from the host and a transmission of a response to the corresponding request to the host, and further configured to determine an operation mode based on a comparison between the adjusted standby entry time and the current host idle interval;
• and
• an operation controller in communication with the operation mode controller to receive information from the operation mode controller on the operation mode and configured to control the memory device according to the operation mode,
• wherein the operation mode controller is further configured to adjust the standby entry time based on a number of first host idle intervals or another number of second host idle intervals, the first host idle intervals successively occurred as a part of the previous host idle intervals and longer than a reference interval and the second host idle intervals successively occurred as another part of the previous host idle intervals and shorter than or equal to the reference interval.
