A memory apparatus includes: a memory cell block; a data input part that performs signal processing to transmit general data and mask information input to the semiconductor memory apparatus to the memory cell block, and outputs the processed data and information; a broadband data line connected between the data input part and the memory cell block; a plurality of registers connected to the broadband data line that writes mask information transmitted through the broadband data line; and a multiplexer that selects mask information from one of the plurality of registers in response to a mask information selection signal, and outputs the selected mask information to the memory cell block.
