Those poor on-chip regulator circuits....
SDRAM had on-chip regulators? I'm guessing it's punching straight through the ESD protection diodes and output driver FETs. Probably hitting bit line pins, since it seems to go chip by chip?

Except it only seems to blow out specific regions and the same regions repeatedly, leaving me to believe it's some kind of on-chip power management at least.

Most of RAM is the array; "always the same region" could easily be an entire logic section, like the output drivers or whatever. AFAIK SDRAM just runs at 3.3V single supply and I'm not aware of any internally generated voltages (or even any real power mgmt beyond self-refresh)
