    摘要: An integrated magnetoresisitive semiconductor memory configuration has MRAM memory cells located at crossover points of selection lines that are embedded in different, mutually separate line planes. A read/write current can be impressed in respective selection lines for writing to each MRAM memory cell and for reading an information item written therein. In this magnetoresistive semiconductor memory configuration, selection lines that serve for reading a cell information item are in each case located in separate first and second line planes in direct contact with the memory cells. A third and a fourth line plane are spatially separated and electrically isolated from the first and second line planes and are occupied by write selection lines for writing a cell information item.

    摘要: A circuit configuration for performing a selective changeover of word lines of a memory matrix between an activation potential and a deactivation potential uses selectively addressable drivers. The changeover of a word line input terminal from the activation potential to the deactivation potential is effected through the relevant driver if a deactivation signal is brought to an active state by a timing control circuit. In order to accelerate the deactivation of the word lines, a respectively assigned deactivation auxiliary switch is connected to each of the word lines at at least one terminal remote from the input terminal. The deactivation auxiliary switch is controlled by a timing control circuit such that it connects the remote terminal to the deactivation potential practically at the same instant at which the assigned driver changes the input terminal of the relevant word line from the activation potential over to the deactivation potential.
