Cyclone FPGA Family Data Sheet
Preliminary Information
Data is written into each address location at the falling edge of the clock
and read from the address at the rising edge of the clock. The shift register
mode logic automatically controls the positive and negative edge clocking
to shift the data in one clock cycle. Figure 14 shows the M4K memory
block in the shift register mode.
