MAGNETIC RANDOM ACCESS MEMORY DEVICE AND METHOD FOR PRODUCING A MAGNETIC RANDOM ACCESS MEMORY DEVICE

摘要

The Magnetic Random Access Memory (MRAM) device has read word lines, write word lines, bit lines, and a plurality of memory bit cells being interconnected via the read word lines, the write word lines and the bit lines, each of the memory bit cells having a fixed ferromagnetic layer element and a free ferromagnetic layer element separated by a dielectric tunnel barrier element, wherein each of the write word lines and a respective number of the free ferromagnetic layer elements are formed as one single, continuous ferromagnetic line.
