The authors report a silicon-based one-diode--type resistive-switching memory (RRAM) device with self-rectifying properties and high electrical properties. The RRAM cell consisted of Al/Cr--SrTiO3/Si and revealed intrinsic diode properties, so that unwanted sneaky currents could be removed from an RRAM crossbar array without extra switching devices. The insulator--metal transition property of the proposed device was explained using the space-charge--limited conduction mechanism. The memory device showed good characteristics including high ON/OFF ratio ({\sim}10^{6}), low reset current ({\sim}10^{-11} A), high speed at low voltage (200 ns, 2 V), and reasonable endurance ({>}10^{4} cycles) and retention characteristics ({>}10^{4} s).
