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.

[7] In 1969 William Regitz and his colleagues at Honeywell invented a three-transistor dynamic memory cell and began to canvass the semiconductor industry for a producer.

The recently founded Intel Corporation responded and developed two very similar 1024-bit chips, the 1102 and 1103, under the lead of Joel Karp, working closely with William Regitz.

[9] Later National Semiconductor, Signetics, and Synertek manufactured the 1103 as well.
