Pulse Transfer Controlling Device
Magnetic Core Memory
Patent Number(s) 2,708,722
An Wang made many notable contributions to the advancement of computer technology, including the magnetic pulse controlling device, the principle upon which magnetic core memory is based.
In 1965 he introduced a desktop computer named LOCI. This forerunner of the Wang electronic desk calculators used a keyboard resembling that of an adding machine but offered the user the unique feature of generating logarithms with a single keystroke. Every year since the production of the first LOCI, Wang and Wang Labs engineers have conceived and designed electronic instruments and systems, maintaining a steady progression of innovations in the office automation and information processing field.
Wang’s pulse transfer controlling device allowed the magnetic field of the cores to control the switching of current in electromagnetic systems. Wang’s other main invention, the write-after-read cycle, also contributed to the overall development of magnetic core memory.
