in thread A perl buffer

you would just say 

use Memoize;

memoize('foo');
sub foo {

}
And if you want to be diligent do a benchmark to see if it is quicker.
Also, make sure that the functions have no side effects (io, setting global/package variables, etc)

    Ahh now I see my problem:
    My function receiving different parameters. For example I configured a database retrive function. As a parameter I receive the sql statement. Sometimes my application will call this retrive function with the same sqlstatement, only in this case I want to memorize it and return the "memorized" image without retriving the data again.
    Now I hope I am clear :)
    BTW thanks everyone for helping.

      that's fine. that is exactly what memoize does. If you called your memoized function with 
      func('select * from table1')
      the second time you ran it with that input, it would simply return the cached value from the first call.
      And that is fine, if you don't care that the data may have changed in the db in the meantime.
