Abstract (en)
[origin: EP0379186A2] A ROM part (24) of a character ROM (21) stores a plurality of font data. A display data RAM (9) simultaneously supplies a plurality of address signals to the character ROM (21) which is provided with a plurality of address decoders (25, 26). Respective address signals are decoded by the corresponding address decoders (25, 26), so that the font data corresponding to the address signals are read on the common bit lines (BL1 - BL l ). Thus, the font data as read are synthesized on the common bit lines (Bl1 - BL l ) as a logical sum.
