Abstract:
Technology for reading reversible resistivity cells in a memory array when using a current-force read is disclosed. The memory cells are first read using a current-force referenced read. If the current-force referenced read is successful, then results of the current-force referenced read are returned. If the current-force referenced read is unsuccessful, then a current-force self-referenced read (SRR) is performed and results of the current-force SRR are returned. In an aspect this mixed current-force read is used for MRAM cells, which are especially challenging to read.
