Following the dynamic state equations, one would be able to violate Landauer's principle of the minimum possible amount of energy required to erase "information" states in a system.<br /><br />Those who are familiar with Landauer's principle and irreversible thermodynamics should have understood what can be read between the lines in the above publication: There are serious concerns that the generalized concept of memristive systems might be related to a modern, electronic version of a "perpetual motion machine of the second kind".Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-13869903.post-58136211359326968942012-08-22T13:36:25.862-05:002012-08-22T13:36:25.862-05:00Is there any response of HP's research to the ...Is there any response of HP's research to the recent publication "Fundamental Issues and Problems in the Realization of Memristors" (on arXiv.org)? There are strong arguments that the physics behind the "memristive systems" approach might be in conflict with Landauer’s principle of the minimum possible amount of energy required to change stored information in a system.

At least there's something substantial there - I think!<br /><br />Nevertheless, it seems to me that the basic distinction is simply that the 'memristor' is nonlinear: voltage goes as current times integral of current. Impedance is by definition a linear property. Once you allow nonlinearity the game changes (to a vastly more complicated one). To claim that the memristor is on a par with the three linear elements is just ridiculous.David Cobdennoreply@blogger.com
