Abstract
A method and apparatus for selecting a rowline in a MRAM device. A rowline select circuit is provided on a first side of each rowline and connects the rowline to ground when a memory cell in the rowline is being written to and to a voltage source when a memory cell in the rowline is being read. A rowline stack select circuit is provided on the second side of each rowline and is connected to one rowline on each plane of memory. When a memory cell is being accessed, the rowline containing that memory cell as well as each other rowline connected to the same rowline stack select circuit are connected to a current source.
