Parameter/Condition
OPERATING CURRENT: One bank; Active-Precharge; t
changing once per clock cyle; Address and control inputs changing once every two clock cycles; (22, 48)
OPERATING CURRENT: One bank; Active-Read-Precharge; Burst = 2; t
Address and control inputs changing once per clock cycle (22, 48)
PRECHARGE POWER-DOWN STANDBY CURRENT: All banks idle; Power-down mode; t
LOW; (23, 32, 50)
IDLE STANDBY CURRENT: CS = HIGH; All banks idle; t
inputs changing once per clock cycle. V
ACTIVE POWER-DOWN STANDBY CURRENT: One bank active; Power-down mode; t
(23, 32, 50)
ACTIVE STANDBY CURRENT: CS = HIGH; CKE = HIGH; One bank; Active-Precharge; t
(MIN); DQ, DM, and DQS inputs changing twice per clock cycle; Address and other control inputs changing once
per clock cycle (22)
OPERATING CURRENT: Burst = 2; Reads; Continuous burst; One bank active; Address and control inputs
changing once per clock cycle; t
OPERATING CURRENT: Burst = 2; Writes; Continuous burst; One bank active; Address and control inputs
changing once per clock cycle; t
AUTO REFRESH CURRENT
SELF REFRESH CURRENT: CKE ≤ 0.2V
OPERATING CURRENT: Four bank interleaving READs (BL=4) with auto precharge, t
(MIN); Address and control inputs change only during Active READ or WRITE commands. (22, 49)
