A 100MHz dual port (DP) MRAM with swing-less bit-line sensing (SLBS) operation for high-end microcomputer systems

In this paper, we propose two kinds of implementations of the dual port MRAM, one of which is for the read/write concurrent operation while another is for the additional simultaneous read operation. Compared with dual port SRAM, the dual port MRAM accompanied with smaller memory cell size will make high performance systems realized in the mobile/robotics field. A swing-less bit-line sensing (SLBS) technique and the static bitline level in the read mode, help to realize the high performance under the condition of V_cc=1.0 V and the operation frequency of 100 MHz
