Claim 0:
1. An apparatus comprising:
a controller to reside on a printed circuit board (PCB) of a memory module, the controller to include circuitry to:
determine, responsive to a first boot of the memory module, a first resistance value for a character pattern sprayed on a side of a heat spreader cover that faces non-volatile memory devices resident on a first side of the PCB, wherein the character pattern is to be sprayed on using conductive ink;
determine, responsive to a second boot of the memory module, a second resistance value for the character pattern; and
assert a bit of a register accessible to the circuitry to indicate tampering of the memory module based on the second resistance value not matching the first resistance value within a threshold resistance value.
