  • Abstract
    In this paper, we propose a C-shaped cell with weakly coupled SAF (WSAF) layer, which features large Hc, small operational switching field and improved robustness against the writing disturbance with large field on hard axis. we have studied astroid curve of C-shaped cell using WSAF free layers, which improve half-selected problem with large field on hard axis. This technology is estimated to be extendable to 256-512Mb MRAM having chip area comparable with DRAM.
