What is the magnetic bubble memory features?

Magnetic bubble memory is a type of non-volatile memory that uses small cylindrical magnetic domains, or "bubbles," to store data. These bubbles can be manipulated and moved using external magnetic fields, allowing for data to be read or written without the need for power. Its key features include high durability, resistance to radiation, and the ability to retain information even when the power is turned off. However, it has largely been replaced by more advanced technologies like flash memory due to slower access times and limited commercial use.
