Clock Modes  
Single-Clock Mode  
Cyclone II memory blocks support single-clock mode for true dual-port,  
simple dual-port, and single-port memory. In this mode, a single clock,  
together with a clock enable, controls all registers of the memory block.  
This mode does not support asynchronous clear signals for the registers.  
Figures 8–18 through 8–20 show the memory block in single-clock mode  
for true dual-port, simple dual-port, and single-port modes, respectively.
