Intel C1103


In 1970, the newly formed Intel company publicly released the 1103, the first DRAM chip (1K bit PMOS dynamic RAM ICs), and by 1972 it was the best selling semiconductor memory chip in the world, defeating magnetic core type memory. The first commercially available computer using the 1103 was the HP 9800 series.

The 1103 had a few drawbacks. By today’s standards it was a primitive device. It was slow, difficult to make, test and operate. But it proved that semiconductor memories were not only viable, but were a vast improvement over core memories, and it greatly increased the power of computers as they then existed.
