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 1):
A memory system, comprising:\n a volatile memory device including a refresh controller connected to memory cells, the volatile memory device being configured to perform a hidden refresh operation on a first portion of the memory cells while the volatile memory device performs a valid operation on a second portion of the memory cells, the refresh controller being configured to generate refresh information based on a number of times the volatile memory device performs the hidden refresh operation during a reference time, a memory controller connected to the volatile memory device, the memory controller being configured to control a schedule for a regular refresh operation based on the refresh information, and the memory controller being configured to control the volatile memory device to perform the regular refresh operation according to the schedule.
