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.
