Transformer Read Only Storage : ウィキペディア英語版 | Transformer Read Only Storage Transformer Read Only Storage (TROS) was a type of ROM used in the '60s and early '70s before solid state memory devices were developed. ==Overview==
The idea of TROS was to create a Read Only Storage method to contain computer microcode. There were several implementation methods used but one notable method used the same technology as core memory that was the primary method of computer memory used during the same period. The specific method was called Core rope memory which used a ferrite core with wires strung through the core like a standard core memory but in some cores one of the wires would be routed around the core itself. The routing of this wire determined the interpretation of a 1 or a 0 with 1 representing a wire that ran through the core and a zero representing a wire that looped around the core.
