Disclosed herein is a technique for created an advanced MRAM array for constructing a memory integrated circuit chip. More specifically, the disclosed principles provide for an integrated circuit memory chip comprised of a combination of at least one of an array of high-speed magnetic memory cells, and at least one of an array of high-density magnetic memory cells. Accordingly, a memory chip constructed as disclosed herein provides the benefit of both high-speed and high-density memory cells on the same memory chip. As a result, applications benefiting from the use of (or perhaps even needing) high-speed memory cells are provided by the memory cells in the high-speed memory cell array.
