More appropriately referred to as the Williams-Kilburn tube, the Williams tube is a storing device for data and cathode-ray tubes (CRT) used with early computers. An application for a patent was originally filed by Freddie Williams in December 11, 1946 and 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."
