Abstract:
A volatile memory device includes a refresh controller configured to control a hidden refresh operation performed on a first portion of memory cells while a valid operation is performed on a second portion of the memory cells. The volatile memory device is configured to perform a regular refresh operation in response to receiving a refresh command. The refresh controller is configured to generate refresh information using a performance indicator of the hidden refresh operation during a first part of a reference time. The volatile memory device is configured to perform a desired number of the regular refresh operation during a remaining part of the reference time based on the refresh information. The desired number of the regular refresh operation is an integer based on a difference between a target number of refresh operations during the reference time and a count value of the hidden refresh operation during the reference time.

Claim (Index 67):
A method of operating a memory system including a volatile memory device connected to a memory controller, the volatile memory device including memory cells connected to a refresh controller, the method comprising:\n performing a first refresh operation on a first portion of the memory cells and a valid operation on a second portion of the memory cells at least one time during a first part of the reference time; generating refresh information using the refresh controller based on a performance indicator of the first refresh operation during the first part of the reference time; providing the refresh information to the memory controller; using the memory controller to schedule a second refresh operation a desired number of times during a remaining part of the reference time, based on the refresh information; and performing the second refresh operation on the volatile memory device during the remaining part of the reference time according to the schedule.
