Delay-line memory is a form of data storage used in the earliest computers such as Leo. This is now reappearing in forms of optical delay lines. Similar to many modern forms of electronic computer memory, delay-line memory were refreshable memory, but as opposed to modern random-access memory, delay-line memory was sequential-access. Mercury delay lines were used in Leo 1 and Leo 2. Mercury was used for its high speed of sound, which means the pulse at the receiving end is far less than in slower mediums such as air. It had to be kept at a constant temperture such as 40 degrees centigrade. This type of memory was used in the late 19th century.
