EABs can be used to implement synchronous RAM, which is easier to use
than asynchronous RAM. A circuit using asynchronous RAM must
generate the RAM write enable signal, while ensuring that its data and
address signals meet setup and hold time specifications relative to the
write enable signal. In contrast, the EAB’s synchronous RAM generates its
own write enable signal and is self-timed with respect to the input or write
clock. A circuit using the EAB’s self-timed RAM must only meet the setup
and hold time specifications of the global clock.
