operation. When the clock-to-clock set-up parameter is vio-
lated for a WRITE-WRITE condition, the contents of the
memory at that location are invalid. When the clock-to-clock
set-up parameter is violated for a WRITE-READ condition,

the contents of the memory are correct, but the read port
has invalid data.
At the first rising edge of the CLKA, memory location 0x00 is
to be written with the value 0xAAAA and is mirrored on the
DOA bus. The last operation of Port B was a read to the
same memory location 0x00. The DOB bus of Port B does
not change with the new value on Port A, and retains the
last read value. A short time later, Port B executes another
read to memory location 0x00, and the DOB bus now
reflects the new memory value written by Port A.
At the second rising edge of CLKA, memory location 0x7E
is written with the value 0x9999 and is mirrored on the DOA
bus. Port B then executes a read operation to the same
memory location without violating the T
the DOB reflects the new memory values written by Port A.
