Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 18:
19. A dual in-line memory module (DIMM) comprising:
a printed circuit board (PCB);
first non-volatile memory devices resident on a first side of the PCB;
second non-volatile memory devices resident on a second side of the PCB;
a first heat spreader cover having a first character pattern sprayed on a side facing the first non-volatile memory devices, wherein the first character pattern is to be sprayed on using conductive ink;
a second heat spreader cover having a second character pattern sprayed on a side facing the second non-volatile memory devices, wherein the second character pattern is to be sprayed on using conductive ink; and
a controller resident on the first side of the PCB, the controller to include circuitry to:
determine, responsive to a first boot of the DIMM, a first resistance value for the first and second character patterns;
determine, responsive to a second boot of the DIMM, a second resistance value for the first and second character patterns; and
assert a bit of a register accessible to the circuitry to indicate tampering of the DIMM based on the second resistance value not matching the first resistance value within a threshold resistance value.
