The M4K RAM block includes support for true dual-port RAM. The M4K RAM block
is used to implement buffers for a wide variety of applications such as storing
processor code, implementing lookup schemes, and implementing larger memory
applications. Each block contains 4,608 RAM bits (including parity bits). M4K RAM
blocks can be configured in the following modes:

When configured as RAM or ROM, you can use an initialization file to pre-load the
memory contents.
M4K RAM blocks allow for different clocks on their inputs and outputs. Either of the
two clocks feeding the block can clock M4K RAM block registers (renwe, address,
byte enable, datain, and output registers). Only the output register can be
bypassed. The six labclk signals or local interconnects can drive the control signals
for the A and B ports of the M4K RAM block. ALMs can also control the clock_a,
clock_b, renwe_a, renwe_b, clr_a, clr_b, clocken_a, and clocken_b
signals, as shown in
