All registers shown have asynchronous clear ports.
Violating the setup or hold time on the address registers could corrupt the memory contents. This applies to both

Independent Clock Mode
The M4K memory blocks implement independent clock mode for true
dual-port memory. In this mode, a separate clock is available for each port
(ports A and B). Clock A controls all registers on the port A side, while
clock B controls all registers on the port B side. Each port, A and B, also
supports independent clock enables and asynchronous clear signals for
port A and B registers.
independent clock mode.
Input/Output Clock Mode
Input/output clock mode can be implemented for both the true and
simple dual-port memory modes. On each of the two ports, A or B, one
clock controls all registers for inputs into the memory block: data input,
wren, and address. The other clock controls the block's data output
registers. Each memory block port, A or B, also supports independent
clock enables and asynchronous clear signals for input and output
registers.
