Abstract

A current driver configuration for MRAMs includes word-line drivers and bit-line drivers at respective first ends of word lines and bit lines. The word line drivers and the bit line drivers each include a series circuit formed by an n-channel field-effect transistor and a current source. Further series circuits are provided at the respective second ends of the word lines and the bit lines. Each of the further series circuits includes a second n-channel field-effect transistor and a voltage source.
