"Sparting Linux"?? That's a 't' (0x74) changing into to a 'p' (0x70). That's a single bit flipping.
Is it always a 1 becoming a 0?

FWIW, it's pretty unlikely to be refresh. DRAM retention at room temperature is waaaay longer than you might think. Nominal refresh timing is spec'ed at TJmax for worst-corner parts, which is orders of magnitude worse than a nominal part at room temperature.

If you're really concerned, hit the stick with a good blast of freeze spray (air duster can inverted will do the trick) and see if it changes anything. Colder -> slower leakage.
