Abstract
A memory device and a control method of the memory device are provided. The memory device includes a memory array and a control logic circuit. The memory array includes memory cell rows. The control logic circuit includes a counter and a reset circuit. The counter counts a number of an access performed on the memory cell rows to generate a count value corresponding to the accessed memory cell row among the memory cell rows, and sets the count value to a random value when the count value is equal to the predetermined value and when the access is performed. The reset circuit resets the count value to a predetermined value in responses to a refresh command. When the count value reaches to the threshold value, the control logic circuit arranges memory cell rows nearby the accessed memory cell row into a mitigation operation.
