Yes? When a given row's counter hits the limit, you refresh every other row which your actually-competent testing has shown might maybe possibly be compromised by that activity.

Same as a good car's computer doesn't make a bunch of rosy assumptions about whether the oil needs changing or not - the automotive engineers actually do their jobs, test the crap out of their engine designs, and base the oil-change criteria on the real-world test results.

(JIC: "Adjacent" has a range of meanings in English. Those go from "the singular closest neighbor, within further constraints on type, orientation, etc." to "relatively close to by some metric". But I am not an EE, let alone a chip architect, to know the "real insider" lingo here.)

Which is the whole chip, because if you only refresh any limited number of rows, the next row outside that range becomes a viable indirect target as shown by Half-Double.

Alternatively you would also count the refresh as a hammer on its adjacent rows.

The later I get into my career the more I'm convinced that the biggest engineering challenge is to convince others there's a problem to begin with. This is also why I think innovation generally only happens in smaller companies: less convincing.
