In this paper, we novel proposed the HPSW-1T1R array to implement hybrid precision Signed-Weight MAC Operation without additional ReRAM array overhead. HPSW-1T1R array can improve the integration by reducing the effects of IR drop and transistor errors at the array level. We demonstrated HPSW-CIM architecture to achieve energy-efficient computing by improving computing density and integration. Simulation shows HPSW-CIM outperforms the state-of-the-art in array computing density and integration while maintaining outstanding energy efficiency.
