Abstract
A magnetic memory of the random access type (MRAM) contains a memory cell array formed of a multiplicity of memory cells. The memory cells are disposed in the form of a matrix at the points of intersection of word lines and sense lines and the logical data contents of which are defined by a magnetic state. The magnetic memory further contains an addressing circuit allocated to the word lines. The address circuit applies a read voltage to the word line of one or more selected memory cells, the data contents of which are to be read out. An evaluation circuit is provided that is allocated to the sense lines and receives and evaluates a sense signal corresponding to the data contents of the selected memory cell or memory cells. The evaluation circuit has a comparator circuit receiving a reference signal supplied by a reference element that is compared with the sense signal of the memory cell or memory cells to be read out.
