Abstract
PURPOSE: To increase the using efficiency of the memory by securing the display driving at the n-th display section with the register output from n to (n + N - 1)- th order and the xtension code desplay bit detection flag and by the output of the address growing circuit in case the data is the extension code.
CONSTITUTION: Memory 505 memorizes the display data in the byte unit and contains the pattern generator to be read out from memory 505. In case the data read out from memory 505 is the non-extension code, the pattern generator is driven by the N-th register and via address growing circuit output 540 to display the patern corresponding to the data at the 1-character display section. And the pattern generator is driven with the output of registers from n to (n + N - 1)-th order plus the output of the extension code display bit detection flag and the pattern obtained is displayed at the n-th display section by output 540 in case the data is the extension code. Thus, the using efficiency can be increased for the memory.
