Note that Power and PowerPC are NOT the same line of processors. Power 4's L3 cache brief can be seem at
http://www-1.ibm.com/servers/eserve...s/power4_4.html

they mount the L3 data arraies on a MCM as the core chip. Examples of MCMs are pentium pro, mobile S3 savage4s, the new geforce 2 go.

Also the main increased cost of using MCM is not the increased mask cost, but rather the yield. [/QUOTE]

MCM?
So they use this kind of package technology.
I think the process-problem can be avoided by using this kind of package.

But Intel or AMD use the same package to combine core and cache?
If they don't, then they still have to face the process problem to deal with logic and memory at same time.

Maybe the redudancy-protect tech. can help some, I still have no not read it carefully. Is it popular in 業界 now?
