PARAMETER/CONDITION
NOTE:
OPERATING CURRENT: One device bank; Active-Precharge;
t
changing once per clock cyle; Address and control inputs
changing once every two clock cycles
OPERATING CURRENT: One device bank; Active -Read Precharge;
Burst = 4;
and control inputs changing once per clock cycle
PRECHARGE POWER-DOWN STANDBY CURRENT: All device banks
idle; Power-down mode;
IDLE STANDBY CURRENT: CS# = HIGH; All device banks idle;
t
changing once per clock cycle. V
ACTIVE POWER-DOWN STANDBY CURRENT: One device bank
active; Power-down mode;
ACTIVE STANDBY CURRENT: CS# = HIGH; CKE = HIGH; One device
bank; Active-Precharge;
DM andDQS inputs changing twice per clock cycle; Address and
other control inputs changing once per clock cycle
OPERATING CURRENT: Burst = 2; Reads; Continuous burst; One
bank active; Address and control inputs changing once per clock
cycle;
OPERATING CURRENT: Burst = 2; Writes; Continuous burst; One
device bank active; Address and control inputs changing once per
clock cycle;
twice per clock cycle
AUTO REFRESH CURRENT
SELF REFRESH CURRENT: CKE
OPERATING CURRENT: Four device bank interleaving READs
(BL = 4) with auto precharge,
Address and control inputs change only during Active READ, or
WRITE commands
