embedded cell (EC) Definition

A memory element that exists in the RAM of supported device ( Cyclone® series, MAX® II , MAX® V, and Stratix® series) families. Embedded cells can implement RAM, ROM, FIFO, or combinational logic.

In Stratix® V devices, the embedded cells are part of the M20K memory blocks. In Stratix® IV devices, the embedded cells are part of the M9K and M144K memory blocks. In MAX® II , and MAX V devices, the embedded cells are part of the M4K memory blocks. In Cyclone® IV devices, the embedded cells are part of the M9K memory blocks. For more details on these memory blocks, see the specific glossary definitions.

Embedded cells have "numbers" of the following format for the following devices:
