A method of forming a MRAM device includes forming an interconnect structure spanning a memory region and a peripheral region; forming a MTJ stack over the interconnect structure within the memory region; depositing a dielectric layer over the MTJ stack and spanning the memory region and the peripheral region; removing a first portion of the dielectric layer from the peripheral region, while leaving a second portion of the dielectric layer within the memory region; after removing the first portion of the dielectric layer from the peripheral region, forming a first IMD layer spanning the memory region and the peripheral region; forming a dual damascene structure through the first IMD layer to a metallization pattern of the interconnect structure within the peripheral region; and after forming the dual damascene structure within the peripheral region, forming a top electrode via in contact with a top electrode of the MTJ stack.
