Gain-Cell Embedded DRAMs: Modeling and Design Space

Andreas Peter Burg, Robert Giterman, Andrea Bonetti, Adam Shmuel Teman

Among the different types of DRAMs, gain-cell embedded DRAM (GC-eDRAM) is a compact, low-power and CMOS-compatible alternative to conventional SRAM. GC-eDRAM achieves high memory density as it relies on a storage cell that can be implemented with as few as ...
