Abstract
A memory device includes a memory medium and a memory controller. The memory medium has a memory cell array and may be configured to generate a self-refresh signal, which varies based on an internal temperature of the memory medium, to control a self-refresh operation performed on the memory cell array. The memory controller may be configured to calculate an auto refresh cycle of an auto refresh control signal for controlling an auto-refresh operation of the memory medium based on the self-refresh signal.
