Address Clock Enable Support
All Stratix IV memory blocks support address clock enable, which holds the previous
address value for as long as the signal is enabled (addressstall = 1). When the
memory blocks are configured in dual-port mode, each port has its own independent
address clock enable. The default value for the address clock enable signals is low
(disabled).
