Abstract:
A memory array storing N*M data values comprising:N rows by M columns of memory elements, each of the N*M memory elements including:(1) a hall effect device capable of carrying an electrical current along a first path; and(2) a ferromagnetic layer with a magnetization state corresponding to one of the N*M stored data values and said magnetization state being coupled substantially perpendicular to said first path to a substantial portion of said electrical current; and(3) wherein an electrical signal related to the magnetization state can be generated at an output of the hall effect device; andwherein N*M distinct electrical signals can be generated corresponding to the N*M data values stored in the N*M memory elements; andisolation elements for isolating the N*M electrical signals and coupled to the N*M memory elements such that each of the N*M memory elements has at least one associated isolation element; anda common bias source coupled to each of the N*M memory elements.
