Memory controller using a memory device with released timing specification according to temperature

摘要

The present invention discloses a memory device used as a timing requirement relaxed with temperature and a memory controller using the same. The memory device has a first timing characteristic at a first temperature, and a second timing characteristic longer than the first timing characteristic at a second temperature. The memory controller controls the first timing characteristic as the timing requirement of the memory device when the temperature of the memory device is higher than the reference temperature, and controls the second timing characteristic as the timing requirement of the memory device when the temperature of the memory device is lower than the reference temperature.
