DISPLAY DEVICE OF MEMORY USING CONDITION

PURPOSE:To know the using condition of a memory through simple operations, by displaying data indicating capacities of a program area, data area, and unused area on the memory through one time of command input and, at the same time, graphically displaying the ratio of each capacity of the areas to the total capacity of the memory. CONSTITUTION:When a command MEM is inputted and an input key 10 is once depressed, data of the capacity A of a program area and data of the capacity B of a data area are respectively outputted to a display buffer. Then the capacity D of the unused area is calculated by subtracting the capacities A and B of the program and data areas from the total capacity C of a user memory and data of the calculated capacity D of the unused area are outputted to the display buffer. A program capacity display section 51 displays the capacity of the program storing area in the number of bytes and a data capacity display section 53 displays the capacity of the data storing area in the number of bytes. A remaining capacity display section 54 displays the capacity of the unused area in the number of bytes. A graphic display section 52 graphically displays respective ratios of capacities of the program storing area, data storing area, and unused area to the total capacity of the user memory.
