Back from the dead..

Thought I'd drop these hopefuls in.

First somebody mentioned SDRAM needing a big cache system to support, and  
that it was unsuitable for Misc type applications.  Well it doesn't and can 
do 2-1-1 timming.  It is unlikely that every fetch will be out of sequence 
in misc so there is a bonus for misc chips, over pdram (which at least in 
consumer terms seems to be getting expensive).  If DDR Dram was meant I am 
unfamiliar with the exacts but as I understand it it uses the same scheme as 
SDRAM but that once accessed the speed is doubled.  I assume that the setup 
timing is the same as SDRAM (but then again I don't know).

It has been said that chips like the f21 have to be manufactured in 100,000 
(or 1 Million lots).  On page 37 of January the 16th's Australian newspaper, 
in the Australianit section, talks about production runs starting AT 5000 
chips. It concerns plans by a Korean company Acqutek (formerly Anam 
Semiconductor) to establish a global custom silicon design studio in 
Melbourne (Aus, sorry ITV) under a subsidary called Semiconductor 
Technologies Australia.  Their customers would get the chips designed and 
manufactured through them, they have an extensive ASIC library to facilitate 
this.  The thing is that this amount of chips is small enough for small 
groups like Ting, ITVcorp to swing (if they accept completed designs for 
manufacturing).  It might even be possible to submit an x21 design as an 
ASIC in their library.

Have fun

Wayne.
