Abstract

PURPOSE: To enable the high speed memory access, by adding a simple hardware to the magnetic bubble chip and its peripheral, and by applying the software used for the magnetic bubble memory unit of minor and major loop system as it is.
CONSTITUTION: On the major line 11 of the magnetic bubble chip of major and minor loop system, one or a plurality of bubble detectors 3 and a plurality of bubble erase and generating unit 4 and 14 are provided, and by inserting a simple information transfer means (for example, shift register) 16 between one or a plurality of bubble detectors and a plurality of bubble erase and generating units 4 and 14, the bubble information during transfer on the major line 11 with the bubble detector 3 is read out to externally, and the information is rewritten in the major line with a plurality of bubble erase and generating units 4 and 14 so that the read out bubble information can be rewritten on the minor loop 1, and the information is written in the major line so that the information from chip external is written on the minor loop with the remaining bubble erase and generating units of a plurality.
