Computer Memory Technology: From Ferrite Rings to FRAM

Magnetic Ferrite-Ring Core Memory When I was a lad back in 1975, I worked as a student engineer testing military aircraft computer memory modules. Looking back now, they probably represented the ultimate development of Ferromagnetic ring core technology. Each module measured about 18 x 10 x 6cm, and contained nearly 600,000 ferrite ring cores providing 32K […]
