jan 6, 1962 - Thin Film Memory

Description:

Thin-film memory is introduced. Sperry Rand developed this faster variation on core memory. Small glass plates held tiny dots of magnetic metal film interconnected with printed drive and sense wires. Used in the UNIVAC 1107 for high-speed registers, it proved too expensive for general use. However, it did find a larger market in military computers and higher end projects where speed was a premium. Several other manufacturers, such as RCA, also developed thin-film memory.
