Core memory, magnetized memory using tiny magnetic rings suspended on a grid of wires, is now more than five decades obsolete, yet it exerts a fascination for hardware hackers still. Not least ...
One way to think of FeRAM is as a very small version of magnetic core memory, with lead-zirconate-titanate (PZT) ferroelectric elements making up the individual bits. These PZT elements are used ...
The world's first DRAM was born in this way: the 1103. Released in 1970, the 1103 surpassed magnetic core memory in just two years and became the best-selling semiconductor memory chip in the world.
