Abstract
A semiconductor device integrated on a chip includes a memory cell array, multiple processing elements and multiple data transfer circuits which transfer data between memory cells and the processing elements over read paths and write paths provided separately. The device is capable of transferring data from memory cells to the processing elements and from the processing elements to memory cells concurrently over the read paths and write paths, respectively, so that faster image data processing is accomplished. The device is also capable of processing data on once-activated word lines successively thereby reducing the number of times each word line is driven so that the power consumption is reduced.
