Abstract: A method for controlling SRAM data read-write, an integrated circuit and a LCD device having the integrated circuit are provided. The method comprises the following steps: writing data into a SRAM in series when a serial read-write pulse signal is at valid level; performing AND operation or OR operation between the serial read-write pulse signal and an internal scan clock signal in the SRAM to generate a parallel read pulse signal, and setting the valid level of the parallel read pulse signal as reverse to the valid level of the serial read-write pulse signal; and reading out the data from the SRAM in parallel when both the internal scan clock signal and the parallel read pulse signal are at valid levels. By setting the valid level of the serial read-write pulse signal and the valid level of the parallel read pulse signal to occur in alternate, the method prevents time sequence conflict between serial read-write and parallel read, and thereby ensures correct data read-write.
