The 1103 is a dynamic random-access memory (DRAM) integrated circuit (IC) developed and fabricated by Intel. Introduced in October 1970, the 1103 was the first commercially available DRAM IC; and due to its small physical size and low price relative to magnetic-core memory, it replaced the latter in many applications.[5][1] When it was introduced in 1970, initial production yields were poor, and it was not until the fifth stepping of the production masks that it became available in large quantities during 1971.
