Williams tube

Updated: 11/13/2018 by Computer Hope

More appropriately called the Williams-Kilburn tube, the Williams tube is a storing device for data and CRT (cathode ray tubes) used with early computers. An application for a patent was originally filed by Freddie Williams on December 11, 1946, and it was finished by Freddie Williams and Tom Kilburn. The tube stored only 128, 40-bit words as an electrical charge that created a spot of light on the face of the "TV tube."
