Parameter/Condition
Operating one bank active-precharge current:
t
HIGH between valid commands; Address inputs are
switching every two clock cycles; Data bus inputs
are stable
Precharge power-down standby current: All banks idle; CKE is LOW;
CS is HIGH,
Data bus inputs are stable
Precharge power-down standby current with clock stopped: All
banks idle; CKE is LOW; CS is HIGH, CK = LOW, CK# = HIGH; Address and
control inputs are switching; Data bus inputs are stable
Precharge non-power-down standby current: All banks idle; CKE =
HIGH; CS = HIGH;
switching; Data bus inputs are stable
Precharge non-power-down standby current with clock stopped:
All banks idle; CKE = HIGH; CS = HIGH; CK = LOW; CK# = HIGH; Address
and control inputs are switching; Data bus inputs are stable
Active power-down standby current: One bank active; CKE = LOW;
CS = HIGH;
Data bus inputs are stable
Active power-down standby current with clock stopped: One
bank active; CKE = LOW; CS = HIGH; CK = LOW; CK# = HIGH; Address and
control inputs are switching; Data bus inputs are stable
Active non-power-down standby current: One bank active; CKE =
HIGH; CS = HIGH;
switching; Data bus inputs are stable
Active non-power-down standby current with clock stopped: One
bank active; CKE = HIGH; CS = HIGH; CK = LOW; CK# = HIGH; Address and
control inputs are switching; Data bus inputs are stable
Operating burst read: One bank active; BL = 4; CL = 3;
I
percent data changing each burst
Operating burst WRITE: One bank active; BL = 4;
