MAGNETIC MEMORY ELEMENT WITH MULTI-DOMAIN STORAGE LAYER

摘要

PURPOSE: A magnetic memory device including a storage layer with a multi-domain is provided to improve data retention performance in a memory cell by securing a plurality of magnetic domains in the storage layer. CONSTITUTION: A programmable memory element has a base layer(122) and a storage layer(130). The base layer has a fixed magnetic orientation. The storage layer is programmed to include a first domain and a second domain. The first domain has magnetic orientation in reverse parallel to the fixed magnetic orientation. The second domain has a magnetic orientation in parallel to the fixed magnetic orientation.
