View Ref-File1.3  RAM                                                          CT60

Upper 40 MHz, the SDRAM is accessed with 1 cycle while the EDO need 2
cycles.

The RAM of the CT60 is equivalent with the TT-Ram (same address :
$01000000).

CT60 is the only one product that uses the SDRAM ! The consequences
on performances are clear :
