The clock-enable control signal controls the clock entering the input and output
registers and the entire M9K memory block. This signal disables the clock so that the
M9K memory block does not see any clock edges and does not perform any
operations.
The rden and wren control signals control the read and write operations for each
port of M9K memory blocks. You can disable the rden or wren signals independently
to save power whenever the operation is not required.
Figure 3–1
the Cyclone III device family M9K memory block.
Parity checking for error detection is possible with the parity bit along with internal
logic resources. The Cyclone III device family M9K memory blocks support a parity
bit for each storage byte. You can use this bit as either a parity bit or as an additional
data bit. No parity function is actually performed on this bit.
