Dual-Port Configuration
As a dual-port RAM, each port of block SelectRAM has
access to a common 18 Kbit memory resource. These are
fully synchronous ports with independent control signals for
each port. The data widths of the two ports can be config-
ured independently, providing built-in bus-width conversion.

ports A and B.
If both ports are configured in either 2K x 9-bit, 1K x 18-bit,
or 512 x 36-bit configurations, the 18 Kbit block is accessi-
ble from port A or B. If both ports are configured in either
16K x 1-bit, 8K x 2-bit. or 4K x 4-bit configurations, the
16 K-bit block is accessible from Port A or Port B. All other
configurations result in one port having access to an 18 Kbit
memory block and the other port having access to a 16 K-bit
subset of the memory block equal to 16 Kbits.
