Has anyone heard of this idea? It apparently delegates some
lower-level computing functions directly to the memory itself, to get
a speedup from doing everything in the CPU. It seems to be an
outgrowth of the “memristor” component that was discovered/invented by
some researchers at HP a few decades ago.

They didn’t have memristors back then, though. This paper uses
memristors
in place of traditional DRAM/SRAM memory cells. The resulting read/write
networks look remarkably like old-style magnetic-core memories, except
that these cells can act as logic gates to perform operations in
parallel.

In a Sph. project, we were given a ferrite core (~1 pound) and were told
to use it as a counter, adding up when a new car entered a parking lot,
and subtracting down when a car left. So, doing arithmetic in ferrite
cores has been around for a very long time, indeed. {{OH, BTW, the
purpose of the count was to prevent overflowing of the parking lot}}
