* 8202 – Dynamic RAM Controller.  This supports the Intel 2104A, 2117, or 2118 DRAM modules, up to 128 KB of DRAM modules. Price was reduced to {{USD|36.25}} for quantities of 100 for the D8202 package style around May 1979.<ref>Intel Corporation, "Microcomputer Components: Intel reduces prices on the 8202, the first single chip, complete solution to dynamic RAM control", Intel Preview, May/June 1979, p. 11.</ref>
* 8203 – Dynamic RAM Controller.  The Intel 82C03 CMOS version dissipates less than 25 mA.  It supports {{dubious-span|text=up to 16x 64K-bit RAM for a total capacity of up to {{val|256|u=KB}}|reason=16 × 65,536 bits = 1,048,576 bits, which equals 131,072 bytes, hence 128KB. The iffy 256KB value was originally added here https://en.wikipedia.org/w/index.php?title=Intel_8085&diff=prev&oldid=1036142833 and I cannot find the cited source.|date=February 2025}}. It refreshes every 10 to 16 microseconds. It supports multiplexing of row and column memory addresses. It generates strobes to latch the address internally. It arbitrates between simultaneous requests for memory access and refresh. It also acknowledges memory-access cycles to the system CPU. The 82C03 was available in either ceramic or plastic packages for {{USD|32.00}} in 100 pieces quantity.<ref>Intel Corporation, "New Product Focus Components: A Refreshing New Dynamic RAM Controller", Solutions, July/August 1984, Page 12.</ref>
