The one example of persistent memory that managed to reach the mass market was Intel Optane/3dXPoint (still popular today among people looking to save on RAM costs) and that used a kind of phase-change memory, which is but tangentially related to memristors. ReRAM is somewhat closer, but it's also been less successful so far.
replyWell, back in the day... The MacIIfx had video memory, ( dual ported ram ) that could be read and written to out of different ports. Wicked fast. It 486DX2s more than a year to catch up.
