PARTITIONED RANDOM ACCESS AND READ ONLY MEMORY

摘要

A magnetic memory and a method of operating the memory are described. The memory includes memory cells that may each include a magnetoresistive bit. The memory cells may each be coupled to a current driver. Each current driver may be inhibited so that it does not output a current. Inhibiting the output current prevents the memory from being written. By inhibiting some current drivers and not inhibiting other current drivers, the memory may be partitioned into read only and random access portions.
