In this paper, we proposed a 28nm 64Kb SRAM based CIM macro, which supports a more complete backward propagation training algorithm. A multiply (MU) unit supports FP and BP modes. A multiply circuit (MC) supports three-inputs-multiplication (TIM) mode for the weight change analog computing. In FP and BP modes, this macro achieves an energy efficiency of 42.1TOPS/W with 2-bit input, 8-bit weight and 14-bit output multiplication and accumulation operations (MAC). In TIM mode, this macro achieves an energy efficiency of 59.4 - 2222TOPS/W with multiplication of 3 inputs and 1 output.
