“Design Considerations” on page 3–15
8,192 memory bits per block (9,216 bits per block including parity)
Independent read-enable (rden) and write-enable (wren) signals for each port
Packed mode in which the M9K memory block is split into two 4.5 K single-port
RAMs
Variable port configurations
Single-port and simple dual-port modes support for all port widths
True dual-port (one read and one write, two reads, or two writes) operation
Byte enables for data input masking during writes
Two clock-enable control signals for each port (port A and port B)
Initialization file to pre-load memory content in RAM and ROM modes
