Switching uniformity, as a major challenge, hinders the practical implementation of \ac{RRAM} in memory application. Operating \ac{RRAM} in current mode, is proposed as an efficient method to improve programming schemes accuracy within the finite readout window. In this article, we demonstrate a current generator circuit to perform current programming on \ac{RRAM}. Current mirror topology is used in our circuit to convert an external pulse voltage into a pulse current fed to \ac{RRAM} directly with an amplitude equivalent with the DC reference current. The targeting ranges of \ac{RRAM}'s programming current are up to 400\,\textmu A and, in that case, our proposed circuit achieved minimum current mismatch of 1\%.
