Magnetic bubble memory component.

摘要

@ A magnetic bubble memory component in the form of a module (1) incorporating a magnetic bubble memory device (10) and analog peripheral circuits therefor (3, 4, 5, 6) mounted on substrate (2) which also carries lead terminals (7). The module (1) can be mounted on a conventional printed circuit board in the manner of other electronic components such as IC's. Further, the module (1) enables a designer with no knowledge of analog circuitry to design memory apparatus utlising the module.

Lead terminals (12) of the device (10) are protected by protection means (8), of insulator such as plastics materials, so that charged bodies (e.g. a human finger) cannot contact those terminals (12). Thereby the possibility of electrostatic charge damage to the device (10) is avoided, affording high reliability and high production yield for memory apparatus using the module (1).
