Conditions
One device bank; Active = Precharge; tRC = tRC(MIN); tCK =
tCK(MIN); DQ,DM and DQS inputs changing once per clock
cycle; Address and control inputs changing once every two
cycles.
One device bank; Active-Read-Precharge; Burst = 2; tRC =
tRC(MIN);tCK = tCK (MIN); Iout = 0mA; Address and control
inputs changing once per clock cycle.
All device banks idle; Power- down mode; tCK = tCK(MIN);
CKE = (low)
CS# = High; All device banks idle; tCK = tCK(MIN); CKE =
high; Address and other control inputs changing once per
clock cycle. VIN = VREF for DQ, DQS and DM.
One device bank active; Power-down mode; tCK(MIN); CKE
= (low)
CS# = High; CKE = High; One device bank; Active-
Precharge; tRC = tRAS(MAX); tCK = tCK(MIN); DQ, DM and
DQS inputs changing twice per clock cycle; Address and
other control inputs changing once per clock cycle.
Burst = 2; Reads; Continuous burst; One device bank active;
Address and control inputs changing once per clock cycle;
tCK = tCK(MIN); IOUT = 0mA.
Burst = 2; Writes; Continous burst; One device bank active;
Address and control inputs changing once per clock cycle;
tCK = tCK(MIN); DQ,DM and DQS inputs changing twice per
clock cycle.
tRC = tRC(MIN)
CKE ≤ 0.2V
Four bank interleaving Reads (BL = 4) with auto precharge
with tRC = tRC (MIN); tCK = tCK(MIN); Address and control
inputs change only during Active Read or Write commands.
