Figure 18. Deep Memory Block Implemented with Multiple ESBs
The ESB implements two forms of dual-port memory: read/write clock
mode and input/output clock mode. The ESB can also be used for
bidirectional, dual-port memory applications in which two ports read or
write simultaneously. To implement this type of dual-port memory, two
or four ESBs are used to support two simultaneous reads or writes. This
functionality is shown in
