This paper proposes the bit-line clamping scheme for a stable signal margin in magnetoresistance RAM. MRAM distinguishes data by the difference of resistance in MTJ. However, there are so many error sources in MTJ that it limits a yield factor. In this paper, we focus on the resistance variation due to bit-line voltage. For maximum signal difference, we try to reduce bit-line voltage as low as possible. Proposed scheme employs CBLSA, equalizer transistor and 1T1MTJ array structure. This method has very excellent bit-line clamping characteristic and overall memory can be designed a simple architecture using current mode sensing. As a result, proposed memory structure can clamp a bit-line voltage under 0.15V and it uses very small power and area. This lower bit-line voltage promises more stable data accessing in MRAM. The circuit is designed in a 0.35μm-CMOS technology.
