Gain cell embedded DRAMs are twice as dense as 6T SRAMs, are logic compatible, have decoupled read and write paths providing good low voltage margin, and can drive long bitlines with gain. In this work, we present a variation study of gain cell eDRAM performance using an industrial 1.2V, 65nm low power CMOS process. Two methods are proposed to analyze eDRAM performance which can be used for designing variation tolerant eDRAM circuits, developing redundancy techniques, and guiding the device optimization procedure.
