Abstract :
The widespread use of multichip module (MCM) technology is currently restricted by high substrate cost, poor substrate yield and low quality level of mounted components: the known good die (KGD) problem. This paper examines three yield enhancing fault tolerance techniques suitable for use with conventional (passive) substrates with the aid of a generic processor-memory MCM architecture. The use of spare memory dies and a paged address space is shown to be a very effective solution to the KGD problem for this particular architecture
