Note:
15. Test conditions assume signal transition time of 3 ns or less, timing reference levels of 1.5V, input pulse levels of 0 to 3.0V, and output loading of the specified
I
/I
and 30-pF load capacitance.
16. To access RAM, CE=L, SEM=H. To access semaphore, CE=H and SEM=L. Either condition must be valid for the entire t
SCE
time.
17. At any given temperature and voltage condition for any given device, t
HZCE
is less than t
LZCE
and t
HZOE
is less than t

.
18. Test conditions used are Load 3.
19. This parameter is guaranteed but not tested. For information on port-to-port delay through RAM cells from writing port to reading port, refer to Read Timing
with Busy waveform.
20. For information on port-to-port delay through RAM cells from writing port to reading port, refer to Read Timing with Busy waveform.
21. Test conditions used are Load 2.
