Summary edit
| Description |
English: Ferrite core memories were used from 1950 to 1975. They retain information without power supply. They required 3 wires per toroid: reading, writing, erasing.
Very high price: $2 per byte in 1970. Good robustness to radiations: used in Space Shuttle Challenger. The development of miniaturized semiconductor memories in high integration circuits has enabled the miniaturization and cost reduction of computer equipments.English: AMPEX computer product division 1973 Magnetic core memory 8192 words of 8 bits here 32768 bits or 32 kBytes |
