[SI-LIST] Re: SOC Limitation

Hi Steve,

Thanks for the reply. I understand that the size of memory than can get
into a chip depends on the foundry process technology. And if the chip is
more memory centric we embed memories higher than 32MB into that chip. 
But I am interested in knowing are there any "other" factors (like Signal
Integrity/Timing/Thermal ), which limit the number of memory cells  into
the SOC

Best Regards,
CK

C K,

Sorry, but I don't see any such quote in that reference.  If it were there
it would be wrong.  How much memory can be embedded in a chip any given
day increases with process technology just like anything else. 

Logic centric chips are structurally different from memory centric chips
and this limits them to a lower memory density than the latter.

Steve.
