ABSTRACT:
Disclosed is a bubble memory system adapted for construction on a single construction unit such as a pluggable card and for providing to prospective users a standard interface including an input data port, an output data port, a clear port, a store enable port, read and write enable ports, register select ports and a clock port. In the memory system, a plurality of bubble memory chips are interconnected in parallel with each of the chips being separately accessed for writing or reading purposes with the aid of the register select ports. Common control of the bubble memory chips is obtained through digitally generated control signals. Low voltage protection is provided by appropriately turning off the in-plane rotating field when the power source exhibits a low voltage condition, thereby protecting the stored data.
