toggling on/off a NAND Flash

Hi everyone,

we have a NAND Flash that stores a configuration which needs to be read 
in chunks on a regular basis. In order to 'protect' the device against 
radiation effects (bit flips, SEFI, SEL, ...) we would like to 
repeatedly power on/off the device, keeping it on just the right time we 
need to access the data.

Considering that the cycle is ~15 seconds and it'll take few 
milliseconds to get the stuff out, would you think that toggling on/off 
at such rates would have an impact on the expected lifetime of the 
component?

I know that capacitors will need to handle some surge at power on, as 
well as the power supply, but except these effects, is there anything 
specific to the device that can suffer from this usage?

Any comment/suggestion/pointer is appreciated.

Al
