Foster's follow up answer is, as well.  propeller

By the way, if one wants to be security conscious, write 00 to the rest of the chip. FF is the state of an erased location, and 00 is fully written. Writing 00 to all unused blocks prevents any further information from being written to those blocks unless the entire chip is erased.

Op-Bell, how do the more sophisticated (and expensive) burners successfully read a chip blind and determine its type, size, and manufacturer?
Well first they have to determine the VCC pin! The really expensive burners have sophisticated pin drivers that can drive any pin to any voltage and determine how much current it draws, so they power up each of the known VCC pins in turn until they find one that has the right characteristics. Then they cautiously raise the voltage on each known possible A9 pin in turn, watching the current, and if it gets up to 12V without looking like it has a protection diode to VCC they try to read the signature. If that fails they go through the other known low-voltage algorithms until one responds.
