Output load: see Figure B, except for tLZC, tLZOE, tHZOE, tHZC, see Figure C.
Input pulse level: GND to 3V. See Figure A.
Input rise and fall time (measured at 0.3V and 2.7V): 2 ns. See Figure A.
Input and output timing reference levels: 1.5V.
VL = 1.5V
for 3.3V I/O;
= VDDQ/2
for 2.5V I/O

Notes:
1) For test conditions, see “AC Test Conditions”, Figures A, B, C
2) This paracmeter measured with output load conditon in Figure C.
3) This parameter is sampled, but not 100% tested.
4) tHZOE is less than tLZOE and tHZC is less than tLZC at any given temperature and voltage.
5) tCH measured HIGH above VIH and tCL measured as LOW below VIL
6) This is a synchronous device. All addresses must meet the specified setup and hold times for all rising edges of CLK. All other synchronous inputs must meet
the setup and hold times with stable logic levels for all rising edges of CLK when chip is enabled.
7) Write refers to R/W, BW[a:d]
.
8) Chip select refers to CE0, CE1, CE2.
