TEMPERATURE EVALUATED EQUIPMENT OF SEMICONDUCTOR RAM(RANDOM ACCESS MEMORY) WITH ENCLOSED CYCLING TYPE

摘要

PURPOSE: A temperature evaluating apparatus of a closed circulation structured semiconductor RAM is provided to change various environmental conditions from low temperature band to high temperature band. CONSTITUTION: A heat exchanger(52) is placed in a direction perpendicular to a semiconductor ram, and bonded with one surface of a heat transmission semiconductor. The air inside the chamber is cooled or heated. A thermoelectric device(50) is welded with the other surface of the heat transmission semiconductor.
