SEMICONDUCTOR MEMORY APPARATUS AND TEMPERATURE CONTROLLING METHOD THEREOF

摘要

The present invention relates to a semiconductor memory apparatus and a controlling method thereof, more specifically to a semiconductor memory apparatus that maintains constant temperature even when the outside temperature changes. The apparatus includes: a cell area having temperature maintenance part that enables a memory cell to maintain constant temperature, and peripheral area that helps the temperature maintenance area to keep a temperature value within the designated range by sensing the temperature of the maintenance area and comparing the temperature with a preset reference temperature.
