Editor's note:

As power and density requirements for embedded memories grow, products ranging from mobile applications to high-performance microprocessors are increasingly looking toward eDRAM as an alternative to SRAM. This article describes the state of the art in eDRAM architecture and design with a particular focus on test challenges and solutions.
