Abstract

PURPOSE:To provide many memory devices, by converting a part of data bit into address bit through the use of address and data buses with a certain line number. CONSTITUTION:A microprocessor 11 is connected to memory package 23 and a display device 19 with an address bus 12 and a data bus 13. The memory package 23 consists of registers 24,25, a decoder 26, memory devices 30,31,32,33 and 34, the address bus 12 is connected to the register 25 and the data bus 13 is connected to the register 24.
