The memory address depths and output widths can be configured as
4,096 × 1, 2,048 × 2, 1,024 × 4, 512 × 8 (or 512 × 9 bits), 256 × 16 (or
256 × 18 bits), and 128 × 32 (or 128 × 36 bits). The 128 × 32- or 36-bit
configuration is not available in the true dual-port mode. Mixed-width
configurations are also possible, allowing different read and write
widths.
configurations.
When the M4K RAM block is configured as a shift register block, you can
create a shift register up to 4,608 bits (w × m × n).
