MAX II programming cycles: 100?

Hello,

I really liked the little MAX II Micro Kit (Terrasic), until I've found it out in the MAX II family datasheet (table 5-3) that the total number of erase/write cycles to the configuration flash is 100? One Hundred? I haven't had such a dramatic disappointment since I learned that Santa is not real.

If this is so, is there a way to configure a MAX II device by updating only the SRAM without touching the flash? It could fix the problem for me, I don't really need permanent changes -- it's for toying around and learning. Can it be done on MAX II in general? On this particular board in particular?

Thanks,

svo

    As far as I see, there is no option to load the configuration to SRAM directly, every reconfiguration involves reprogramming of the CFM. I wonder however, if the expectable endurance is actually near to the said 100 programming cycles? Most CPLD have a minimum of 1000, and hopefully MAX II can stand it typically.
