Abstract

PURPOSE:To convert an electrically erasable programmable read only memory and a control memory, to a small capacity, and to make them economical, by storing only a microprogram required for the information processing system concerned, in each control memory. CONSTITUTION:An initializing means 100 inspects whether a memory card 4 is installed or not, when a power source is turned on, and when the memory card 4 is installed, a microprogram MP stored in the memory card 4 is extracted and stored in an electrically erasable programmable read only memory 6, and subsequently, the microprogram MP stored in the read only memory 6 is extracted and stored in a control memory 1a. Accordingly, by storing only the microprogram required for an information processing system being each object, in the memory card 4, only the microprogram required for the information processing system concerned is stored in each control memory. In such a way, the read only memory 6 and the control memory 1a are make economical.
