Abstract

PURPOSE: To make the volume of transfer data unlimited by reading address data by making it possible to exercise individual control by providing a data bus where read and write data are transferred and an address bus for transferring address information.
CONSTITUTION: Once address information is input to address register 15, magnetic bubbles are actuated to transfer address information to read enable generating circuit 14, and bus driver 16 is put into operation. Then, read-write unit 17 reads data on magnetic bubble chip 18 and when the signal and an enable signal meet AND conditions, data are stored in register 12 via driver 16 and address bus 3. The outputs of registers 12 and 15 are compared to each other by comparing circuit 13 and written on chip 18 by write unit 17 by way of register 11 and data bus 4 and data on chip 18 are read by read unit 17 and written in register 11 via data bus 4. Therefore, the volume of transfer data is unlimited by reading address data.
