Abstract
To speed up data transfer of a plurality of registers between register banks in a microcomptuer having a register file formed by a built-in RAM and consisting of a plurality of register banks, the memory cells of the same type of registers belonging to different register banks are connected to the same bit lines. For data transfer of a plurality of registers between register banks, the word line 12 connecting a source register bank is first activated to output data to bit lines 13, and then the word line 12 connecting to a destination register bank is activated to read the data outputted to the bit lines 13, thus making it possible to speed up data transfer of a plurality of registers without the use of the internal data bus 3 of the microcomputer.
