Comments on “Overdriving approximation”


Usualness, adversaries, row hammer

Peter's picture

Reading footnote 4 reminded me of row hammer - a security exploit in DRAM that flips normally-inaccessible bits in memory by repeatedly accessing physically nearby rows of memory, thereby using charge leakage. I think that usualness conditions become particularly fraught when there’s an adversary out there who’s deliberately looking for exceptions to the conditions, in order to exploit them.

Some missing graphs in Overdriving approximation

The first couple of graphs seem to be missing, I see this:

Graphed, this is a straight line:

The model is not absolutely true. For small enough positive or negative

Missing graphs

Ah, thanks for pointing that out… I need to figure out what program to use to make the plots, learn to use it, and make them, and I keep putting that off!
