Abstract :
It suggests the life time model of DRAM device which is related with oxide thickness (Tox) and stress voltage. The life time model is composed of the exponential relationship from Mil-HDBK-217E (1986) and the relationship between β (Experimental constant) and Tox which is based on E-Model. This suggested model imply that the life time of packaged device at an ART could be affected by the failure time distribution as well as induced E-field at a given temperature
