Read Only Memory (ROM)
If two dual-port 16 x 1-bit modules are built, the two RAM16X1D primitives can occupy
two slices in a CLB, as long as they share the same clock and write enable, as illustrated in
Figure
The RAM64X1S primitive occupies two slices. The RAM64X1S read path is built on the
MUXF5 and MUXF6 multiplexers.
Each function generator in SLICEM and SLICEL can implement a 16 x 1-bit ROM. Four
configurations are available: ROM16x1, ROM32x1, ROM64x1, and ROM128x1. The ROM
elements are cascadable to implement wider and/or deeper ROM. ROM contents are
loaded at device configuration.
