Bubble memory is a type of non-volatile computer memory that uses a thin film of a magnetic material to hold small magnetized areas, known as bubbles or domains, each storing one bit of data. Bubble memory started out as a promising technology in the 1970s, but failed commercially as hard disk performance and cost improvements in the 1980s overtook its advantages.

Famous quotes containing the words bubble and/or memory:
“Each swung in danger on its slender twig,
A bubble on a pipestem, growing big.”
—Robert Frost (1874–1963)
“I hope there will be no effort to put up a shaft or any monument of that sort in memory of me or of the other women who have given themselves to our work. The best kind of a memorial would be a school where girls could be taught everything useful that would help them to earn an honorable livelihood; where they could learn to do anything they were capable of, just as boys can. I would like to have lived to see such a school as that in every great city of the United States.”
—Susan B. Anthony (1820–1906)
