Introduced in 1970, the Intel 1103 is the first commercially available DRAM. The 1103 is a 1kbit PMOS device based on a three-transistor memory cell, designed in 1969 by Honeywell engineer William Regitz. The 1103 was Intel's breakout product, displacing core memory as the predominant technology and establishing Intel as the leading pioneer in semiconductor RAM.

Perhaps the most noteworthy customer of the Intel 1103 was Hewlett-Packard, who assisted Intel in improving the 1103 design and implemented the 1103 as the primary memory in their early 9800-series desktop calculators.
