Spin-Dependent Electron Transport in MeRAM

The paper presents theoretical model of a straintronics magnetoelectric random-access memory (MeRAM) storage cell with configurational anisotropy. The MeRAM cell consists of ferromagnetic layers with different orientations of the quasi-uniform magnetization, which is divided into identical magnetic tunnel junction’s ferromagnet|insulator|ferromagnet, in the form of a sandwich of planar layers. The modified theory for magnetic tunnel junction is used to calculate the spin-dependent current and tunnel magnetoresistance like functions of orientations magnetizations of layers.
