National High Magnetic Field Laboratory in Florida enables you to see the magnetic core memory process in motion: head over to take a look at it.
By the time it was finally usurped as the prime RAM technology, core memory access speeds were down to nearly a single microsecond – just 1.2ms. However, the time of core memory was very nearly up. A team at Bell Labs had been developing a revolutionary technology – the transistor – since 1948. 20 years later, that technology would change the face of computing almost overnight.
The first RAM chip
The first commercial transistors were small, cheap and above all, reliable. Transistors soon took over from bulky and unreliable glass valves as the main component of the logic gates and registers in the CPUs of the early 1950s.
