A controlling apparatus and a controlling method for controlling a pre-charge activity on a SRAM array are provided. The controlling apparatus comprises: a detecting module, a controlling module and a pre-charge module. The detecting module is to detect whether the row address of the SRAM array in operation is changed and generate a row-changing signal according to the detection result; the controlling module is to detect an operation mode of the SRAM array and generate a disable signal according to the row-changing signal and the operation mode; and the pre-charge module is to generate a pre-charge signal according to a pseudo-pre-charge signal and the disable signal, wherein the pre-charge signal substantially controls the pre-charge activity on the SRAM cell in operation.
