Operating Current - One bank, Activate - Precharge
t_CK=min(t_CK), t_RC=min(t_RC)
Databus inputs are SWITCHING; Address and control inputs are SWITCHING, CS = HIGH between valid
commands.
Operating Current - One bank, Activate - Read - Precharge
One bank is accessed with t_CK=min(t_CK), t_RC=min(t_RC), CL = CL(min), Address and control inputs are SWITCHING;
CS = HIGH between valid commands. I_out=0 mA
Precharge Power-Down Standby Current
All banks idle, power-down mode, CKE is LOW, t_CK=min(t_CK), Data bus inputs are STABLE (HIGH).
Precharge Floating Standby Current
All banks idle; CS is HIGH, CKE is HIGH, t_CK=min(t_CK); Address and control inputs are SWITCHING; Data bus input
are STABLE (HIGH).
Precharge Quiet Standby Current
CS is HIGH, all banks idle, CKE is HIGH, t_CK=min(t_CK), Address and other control inputs STABLE (HIGH), Data
bus inputs are STABLE (HIGH).
Active Power-Down Standby Current
One bank active, CKE is LOW, Address and control inputs are STABLE (HIGH); Data bus inputs are STABLE
(HIGH); standard active power-down mode.
Active Standby Current
One bank active, CS is HIGH, CKE is HIGH, t_RAS= t_RAS,max, t_CK=min(t_CK); Address and control inputs are
SWITCHING; Data bus inputs are SWITCHING.
Operating Current - Burst Read
One bank active; Continuous read bursts, CL = CL(min); t_CK=min(t_CK); t_RAS= t_RAS,max; Address and control inputs
are SWITCHING; Iout = 0 mA.
Operating Current - Burst Write
One bank active; Continuous write bursts; t_CK=min(t_CK); Address and control inputs are SWITCHING; Data bus
inputs are SWITCHING.
Burst Auto Refresh Current
Refresh command at t_RFC=min(t_RFC); t_CK=min(t_CK); CKE is HIGH, CS is HIGH between all valid commands; Other
command and address inputs are SWITCHING; Data bus inputs are SWITCHING.
Distributed Auto Refresh Current
t_CK=t_CKmin; Refresh command every t_REFI; CKE is HIGH, CS is HIGH between valid commands; Other command
and address inputs are SWITCHING; Data bus inputs are SWITCHING.
