摘要： Method and apparatus for testing a magnetic bubble memory are disclosed wherein a most severe magnetic bubble domain arrangement which fully causes the ununiformity of magnetic interaction between magnetic bubble domains is experimentally determined, and a basic pattern [P] and a test information pattern determining an arrangement of the basic patterns [P] and complementary patterns [P] thereof for realizing that magnetic bubble domain arrangement are stored in memory units, respectively, and the basic patterns [P] and the complementary patterns [P] are sequentially read out in accordance with the test information pattern to generate magnetic bubble domain trains in a storage area of the magnetic bubble memory. The magnetic bubble domain trains are then read out by a magnetic bubble detector and the read-out signals are converted to logical signals by a sense amplifier unit and the logical signals are synchronized with logical signals corresponding to the test information pattern and compared therewith to produce an identity or non-identity signal and thus the disclosed method and apparatus for testing the magnetic bubble memory can exactly evaluate a memory characteristic of the magnetic bubble memory.
