Email:[email protected] Abstract A high performance eDRAM technology has been developed on a high-performance and low-power 22nm tri-gate CMOS SoC technology. By applying noise reduction circuit techniques and extensive device and design co-optimization on eDRAM bitcell and critical circuits, over 100μs retention time at 95°C has been achieved for a Gbit eDRAM with robust manufacturing yield.
