Stratix III M9K/M144K true-dual-port support 1/2 the max width.

page 4-13:

The widest bit configuration of the M9K and M144K blocks in true dual-port mode is as follows:

■ 512 × 16-bit (×18-bit with parity) (M9K)

■ 4K × 32-bit (×36-bit with parity) (M144K)

Wider configurations are unavailable because the number of output drivers is equivalent to the maximum bit width of the respective memory block. Because true dual-port RAM has outputs on two ports, its maximum width equals half of the total number of output drivers.

Thanks for making me feel better about not being the only one to miss it the 1st time thru. :) -Brian
