bubble memory



  • noun a method of storing binary data using the magnetic properties of certain materials, allowing very large amounts of data to be stored in primary memory


  • A type of non-volatile computer memory that utilizes materials, such as crystals, to retain a magnetic polarity. This polarity determines whether ones or zeroes are being stored, and with the assistance of permanent magnets, also serves to retain the stored information in case power is cut off. Used primarily for rugged computing circumstances. Also called bubble storage, or magnetic bubble memory.
