Abstract
A memory device may include a time counter which is configured to output a count signal according to a predetermined time interval; a use history circuit which is configured to write an operating time value based on the count signal and generate and write a validation value corresponding to the operating time value; and a command decoder which is configured to receive an instruction from a memory controller. The instruction may be according to an operation mode that is determined based on the operating time value and the validation value.
