Abstract
A 4 Mbit Magnetoresistive Random Access Memory (MRAM) with a new magnetic switching mode is described. The memory cell is based on a 1-Transistor 1-Magnetic Tunnel Junction (1T1MTJ) bit cell. The 4 Mbit MRAM circuit was designed in a five level metal, 0.18 /spl mu/m CMOS process with a bit cell size of 1.55 /spl mu/m/sup 2/. A new cell architecture, bit structure, and switching mode improve the operational performance of the MRAM as compared to conventional MRAM. The 4 Mbit circuit is the largest MRAM memory demonstration to date.
