Cyclone III device family M9K memory blocks allow you to implement
fully-synchronous SRAM memory in multiple modes of operation. Cyclone III device
family M9K memory blocks do not support asynchronous (unregistered) memory
inputs.
M9K memory blocks support the following modes:

Violating the setup or hold time on the M9K memory block input registers may
corrupt memory contents. This applies to both read and write operations.
Single-port mode supports non-simultaneous read and write operations from a single
address.
