(Field value contents in blue font or parentheses are optional AC parameter and CL setting)
1. All speed grades support 0°C
≤ T
CASE
≤ 85°C with full JEDEC AC and DC specifications.
2. The -09, -11, -12 and -15 speed grades, -40°C
≤ T
CASE
< 0°C is not available.
3. The 09I, 09J, 11I, 11J, 12I, 12J, 15I and 15J speed grades support -40°C
≤ T
CASE
≤ 85°C with full JEDEC AC and DC
specifications.
4. The -09, 09I, -11, 11I, -12, 12I, -15 and 15I speed grades, T
CASE
is able to extend to 95°C. The 09J, 11J, 12J and 15J speed
grades, T
CASE
is able to extend to 105°C. They are with doubling Auto Refresh commands in frequency to a 32 mS period ( t
REFI
= 3.9 µS), it is mandatory to either use the Manual Self-Refresh mode with Extended Temperature Range capability (MR2 A6 = 0
b
and MR2 A7 = 1
b
) or enable the Auto Self-Refresh mode (ASR) (MR2 A6 = 1
b
, MR2 A7 is don't care).
5. For devices supporting optional down binning to CL=7 and CL=9, t
AA
/t
RCD
/t
RP
min must be 13.125 nS or lower. SPD settings must be
programmed to match. For example, DDR3L-1333 (9-9-9) devices supporting down binning to DDR3L-1066 (7-7-7) should program
13.125 nS in SPD bytes for t
AA
min (Byte 16), t
RCD
min (Byte 18), and t
RP
min (Byte 20). DDR3L-1600 (11-11-11) devices supporting
down binning to DDR3L-1333 (9-9-9) or DDR3L-1066 (7-7-7) should program 13.125 nS in SPD bytes for t
AA
min (Byte16), t
RCD
min
(Byte 18), and t
RP
min (Byte 20). Once t
RP
(Byte 20) is programmed to 13.125 nS, t
RC
min (Byte 21, 23) also should be programmed
accordingly. For example, 49.125nS (t
RAS
min + t
RP
min = 36 nS + 13.125 nS) for DDR3L-1333 (9-9-9) and 48.125 nS (t
RAS
min +
t
RP
min = 35 nS + 13.125 nS) for DDR3L-1600 (11-11-11).
6. For devices supporting optional down binning to CL=11, CL=9 and CL=7, t
AA
/t
RCD
/t
RP
min must be 13.125 nS. SPD settings must be
programmed to match. For example, DDR3L-1866 (13-13-13) devices supporting down binning to DDR3L-1600 (11-11-11) or
DDR3L-1333 (9-9-9) or DDR3L-1066 (7-7-7) should program 13.125 nS in SPD bytes for t
AA
min (Byte 16), t
RCD
min (Byte 18), and
t
RP
min (Byte 20). Once t
RP
(Byte 20) is programmed to 13.125 nS, t
RC
min (Byte 21, 23) also should be programmed accordingly. For
example, 47.125nS (t
RAS
min + t
RP
min = 34 nS + 13.125 nS).
