ABSTRACT:
A memory device having an operating function includes a memory cell array, a register, and a logical opeation circuit. The memory cell array has memory cells arranged in a matrix form of m rows .times.n columns. Data readout or write-in operation with respect to the memory cell array is effected in the unit of n bits of one row. The register has a bit width corresponding to one row of the memory cell array. Data of one row is read out from the memory cell array and is processed by the logical operation circuit together with data stored in the register. The result of operation is written into a desired row of the memory cell array. The memory cell array, register, and logical operation circuit are formed in the same integrated circuit, thus permitting processing such as picture element processing to be effected inside the integrated circuit, without the need to use an external data bus.
