PURPOSE: A data storage apparatus including an encoding output function and system thereof are provided to offer reinforced data security functions by randomly setting an encoding method for each part of the whole data. CONSTITUTION: A control unit(14) decodes the inputted command. The control unit outputs internal read signals or internal trigger signals according to decoding results. A memory unit(12) outputs data by receiving the internal read signals. An encoding unit(16) creates mode-determination basic data by responding to the internal trigger signal.
