The aim of this paper is to propose a real time reconfigurable (RTR) micro-FPGA using new non volatile memory. Magnetic tunneling junctions (MTJ) used in Magnetic random access memories (MRAM) are compatible with classical CMOS processes. Moreover remanent property of such a memory could limit configuration time and power consumption required at each power up of the die. Nevertheless, each configuration memory point has to be readable independently from each other, that is why the approach is different from the classical memory array one.
