Memory Density
By the standards of the time, a relatively large amount of data could be stored in a small installed volume of core rope memory: 72 kilobytes per cubic foot, or roughly 2.5 megabytes per cubic meter. This was about 18-folda the amount of data per volume compared to standard read-write core memory.

| Core rope ROM | 72 KB | 576 Kbit | ~2.5 MB | ~20 Mbit |
| Magnetic core RAM | 4 KB | 32 Kbit | ~140 KB | ~1 Mbit |

Famous quotes containing the word memory:
“What has kept the world safe from the bomb since 1945 has not been deterrence, in the sense of fear of specific weapons, so much as it’s been memory. The memory of what happened at Hiroshima.”
—John Hersey (b. 1914)
