Abstract
A memory device used with a relaxed timing requirement specification according to temperatures, an operation method thereof, and a memory controller and a memory system using the memory device are provided. The memory device has a first timing characteristic at a first temperature and a second timing characteristic that is longer than the first timing characteristic at a second temperature. If a temperature of the memory device is higher than a reference temperature, the memory controller controls the first timing characteristic as a timing requirement specification of the memory device. If the temperature of the memory device is lower than the reference temperature, the memory controller controls the second timing characteristic as the timing requirement specification of the memory device.
