摘要
A low-power 2Mb ReRAM macro was developed in 90 nm CMOS platform, demonstrating lower power data-writing (x1/7) and faster data-reading (x2 similar to 3) as compared to a conventional flash. The memory window at -6 sigma for 10 years was confirmed with a high-speed 1-bit ECC considering operating temperature ranging from -40 to 85 degrees C, where the worst conditions are high-temperature (85 degrees C) "Off" writing and low-temperature (-40 degrees C) "On" writing followed by high-temperature (85 degrees C) retention. A pulse-modulated Off-state verify and an interface-control of Ru electrode are effective for suppressing random fluctuation of R-off readout and for sustaining the On-state retention, respectively.
