Figure 18. RAM Memory Port Configurations

Note to Figure 18:

(1)

Two dual- or single-port memory blocks can be implemented in a single ESB.

The ESB also allows variable width data ports for reading and writing to

any of the RAM ports in any RAM configuration. For example, the ESB in

quad port configuration can be written in

×1 mode at port A, read in ×16

from port A, written in

×4 mode at port B, and read in ×2 mode from

port B.
