In this paper, we propose a current memory circuit design that reduces static power consumption and maximizes the advantages of current mode signal processing. The proposed current memory circuit minimizes the problem in which the current transfer error increases as the data transfer time increases due to clock-feedthrough and charge-injection of the existing current memory circuit. The proposed circuit is designed to insert a support MOS capacitor that maximizes the Miller effect in the current transfer structure capable of low-power operation. As a result, it shows the improved current transfer error according to the memory time. From the experimental results of the chip, manufactured with MagnaChip / SK Hynix 0.35 process, it was verified that the current transfer error, according to the memory time, reduced to 5% or less.
