Beschreibung
Zusammenfassung:A computer module is disclosed in which a stack of glued together IC memory chips is structurally integrated with a microprocessor chip. The memory provided by the stack is dedicated to the microprocessor chip. The microprocessor and its memory stack may be connected either by glue and/or by solder bumps. The solder bumps can perform three functions-electrical interconnection, mechanical connection, and heat transfer. The electrical connections in some versions are provided by wire bonding.
