Parameter/Condition
Operating one bank active-precharge current:
t
Address and control inputs changing once every two clock cycles
Operating one bank active-read-precharge current: BL = 2;
t
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;
CKE = HIGH; Address and other control inputs 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;
t
clock cycle; Address and other control inputs changing once per clock cycle
Operating burst read current: BL = 2; Continuous burst reads; One device
