摘要
A 16Mb Magnetic Random Access Memory (MRAM) is demonstrated in 0.18mum three-Cu-level CMOS with a three-level MRAM process adder. The chip, the highest density MRAM reported to date, utilizes a 1.42mum(2) 1-Transistor 1-Magnetic Tunnel Junction (1T1MTJ) cell, measures 79mm(2) and features a x16 asynchronous SRAM-like interface. The paper describes the cell, architecture, and circuit techniques unique to multi-Mb MRAM design, including a novel bootstrapped write driver circuit. Hardware results are presented.
