Clock - CLK[A|B]
Enable - EN[A|B]
RAMB16 is the block RAM library primitive. It is the basic building block for all block
RAM configurations. Other block RAM primitives and macros are based on this primitive.
Some block RAM attributes can only be configured using this primitive (e.g., pipeline
register, cascade). See
Figure 4-9
Each block RAM port operates independently of the other while accessing the same set of
18 Kbit memory cells.
Each port is fully synchronous with independent clock pins. All port input pins have setup
time referenced to the port CLK pin. The output data bus has a clock-to-out time
referenced to the CLK pin. Clock polarity is configurable (rising edge by default).
The enable pin affects the read, write, and set/reset functionality of the port. Ports with an
inactive enable pin keep the output pins in the previous state and do not write data to the
memory cells. Enable polarity is configurable (active High by default).
illustrates all the I/O ports of the block RAM primitive (RAMB16).
