Notes :1. AC measurement assumes
t
T
= 1ns. Reference level for timing of input signals is 1.40V.
If
t
T
is longer than 1ns,transition time compensation should be considered.
2. Access time is measured at 1.40V. Load condition is C
L
= 50pF without termination.
3.
t
LZ
(min)defines the time at which the outputs achieves the low impedance state.
4.
t
HZ
(max)defines the time at which the outputs achieves the high impedance state.
5.
t
CES
define CKE setup time to CKE rising edge except Power down exit command.
Test Condition
Input and output-timing reference levels: 1.4V
