Magnetic random access memory (MRAM) cell with a thermally assisted switching writing procedure and methods for manufacturing and using same. The MRAM cell includes a magnetic tunnel junction that has at least a first magnetic layer, a second magnetic layer, and an insulating layer disposed between the first and a second magnetic layers. The MRAM cell further includes a select transistor and a current line electrically connected to the junction. The current line advantageously can support a plurality of MRAM operational functions. The current line can fulfill a first function for passing a first portion of current for heating the junction and a second function for passing a second portion of current in order to switch the magnetization of the first magnetic layer.
