It needlessly uses slices.

Using a (single) slice I would probably do:

for (@{$memoryfile}[0,1]) {
    LogMess("Error: Binary input data detected",1), 
      return -1 if /[^[:print:]]/;
}

Somewhat of an overkill for just two values, but IMHO clearer and also easy to modify if you want something more than 0 and 1 there...
