ALL meanings of bubble memory
bub·ble mem·o·ry
B b - noun bubble memory a method of storing high volumes of data by the use of minute pockets of magnetism (bubbles) in a semiconducting material. The bubbles may be caused to migrate past a read head or to a buffer area for storage 3
- noun bubble memory a solid-state computer memory device that stores bits of data by means of magnetized, microscopic areas (magnetic bubbles) in sheets of a semiconductor 3
- noun bubble memory a storage medium employing tiny, movable, bubble-shaped magnetized areas within a magnetic material to represent data bits. 1
- noun Definition of bubble memory in Technology A storage device built using materials such as gadolinium gallium garnet which are can be magnetised easily in only one direction. A film of these materials can be created so that it is magnetisable in an up-down direction. The magnetic fields tend to join together, some with the north pole facing up, some with the south. When a veritcal magnetic field is imposed on this, the areas in opposite alignment to the field shrink to circles, or 'bubbles'. A bubble can be formed by reversing the field in a small spot, and can be destroyed by increasing the field. Bubble memory is a kind of non-volatile storage but EEPROM, Flash Erasable Programmable Read-Only Memory and ferroelectric technologies, which are also non-volatile, are faster. 1
- noun bubble memory (computing) A type of non-volatile computer memory that uses a thin film of magnetic material to hold small magnetized areas, known as bubbles or domains, each storing one bit of data. 0
