Magnetic cores have a few properties that made core memory work. This experimental system was tested successfully in April 1952. What does magnetic-core memory mean? The core can take two states, encoding one bit, which can be read when "selected" by a "sense wire". Limits. Ex : fille - nf > On dira "la fille" ou "une fille". It is by implication a nice attack on the integrity of Wang. Example sentences with "magnetic core memory", translation memory. 7 By passing a strong current along a wire through the core, the core becomes magnetized, either clockwise or counterclockwise depending on the direction of the current. Aside from being extremely reliable, magnetic core memory is an appealing technology because it is based on a very simple idea. E.g. The memory made use of magnetic rings called cores that had wires passing through them for selecting and detecting the contents of the cores. core storage A non-volatile memory that holds magnetic charges in tiny ferrite cores.

In the 1950s and 1960s, these methods were largely supplanted by magnetic storage devices such as magnetic core memory, magnetic tapes, drums, and disks, where a bit was represented by the polarity of magnetization of a certain area of a ferromagnetic film, or by a change in polarity from one direction to the other.

Forrester and Dr. ATTORNEYS United States Patent O 3,161,861 MAGNETEC CORE … Core memory was the dominant form of computer storage from the 1950s until it was replaced by semiconductor memory chips in the 1970s. Organised as 64 rows by 64 columns, this Univac III core memory plane of early 60's vintage has a storage capacity of 4096 bits. Meaning of magnetic-core memory. Magnetic-core memory was the predominant form of random-access computer memory for 20 years between about 1955 and 1975. Core memory was a common form of random access memory (RAM) from the mid-1950s to the mid-'70s, and It was developed at MIT in 1951. This magnetic read-only memory (ROM), contrary to ordinary coincident-current magnetic core memories (used for RAM), uses the ferrite cores as transformers. A core was magnetized by sending a pulse of current through wires threaded through the core. Core Memory. Noté /5. Magnetic core memory, also known as Forrester memory or ferrite-core memory, is an early form of random access computer memory. MAGNETIC CORE MEMORY Filed Nov. 12, 1959 2 sheets-sheet 1 X WRITE REGULATED POWER SUPPLY E/CHAED L 5557' ATTORNEYS v Dec. 15, 1964 K. H. oLsEN ETAL 3,161,861 . Principle: Magnetic core memory is formed by an array of ferrite toroids with wires passing through it. Magnetic core memory was the most widely used form of digital computer memory from its birth in the early 1950s until the era of integrated-circuit memory began in the early 1970s. It used tiny magnetic rings, or cores, with wires running through the centre and because the cores are so small seamstresses were used to thread the wires through the cores!
