Abstract: The present disclosure concerns a magnetic random access memory cell containing a magnetic tunnel junction formed from an insulating layer comprised between a sense layer and a storage layer. The present disclosure also concerns a method for writing and reading the memory cell comprising, during a write operation, switching a magnetization direction of said storage layer to write data to said storage layer and, during a read operation, aligning magnetization direction of said sense layer in a first aligned direction and comparing said write data with said first aligned direction by measuring a first resistance value of said magnetic tunnel junction. The disclosed memory cell and method allow for performing the write and read operations with low power consumption and an increased speed.
