Low Power NanoCrossbar Resistives Memory, Nature Journal

Scientists from the Jülich-Aachen Research Alliance (JARA) have a new paper coming out in Nature Materials journal with the title “Complementary resistive switches for passive nanocrossbar memories”. The Complementary Resistive Switch in the paper is stated to provide a solution to the problem of crosstalk between memristive cells adjacent to each other in a memristive array. This is part of the transputer problem that arises in the John von Neumann architecture of the separation of memory and logic, and a step forward in tighter coupling of memory and logic, reducing power consumption:

A member of Waser’s group from RWTH Aachen University, Eike Linn, and his colleagues Roland Rosezin and Carsten Kügeler, both from Forschungszentrum Jülich, solved this challenge by developing a completely new switching concept. This concept is based on the antiserial switching of two memristive cells. Together, these cells form a novel unit, which the scientists termed a CRS cell (complementary resistive switch). No undesirable superimposition of information takes place between CRS cells. [..edit..] The necessary data transport between the functional areas thus leads to high energy consumption.
