LatticeXP Family Data Sheet
The Lattice design tools support the creation of a variety of different size memories. Where appropriate, the soft-
ware will construct these using distributed memory primitives that represent the capabilities of the PFU. Table 2-3
shows the number of Slices required to implement different distributed RAM primitives. Figure 2-4 shows the dis-
tributed memory primitive block diagrams. Dual port memories involve the pairing of two Slices, one Slice functions
as the read-write port. The other companion Slice supports the read-only port. For more information on RAM mode
in LatticeXP devices, please see details of additional technical documentation at the end of this data sheet.

ROM Mode: The ROM mode uses the same principal as the RAM modes, but without the Write port. Pre-loading is
accomplished through the programming interface during configuration.
PFU Modes of Operation
Slices can be combined within a PFU to form larger functions. Table 2-4 tabulates these modes and documents the
functionality possible at the PFU level.
