JEDEC Standard No. 79-3-1A.01
Page 1
1.35 V DDR3-800, DDR3L-1066, DDR3L-1333, DDR3L-1600, and DDR3L-1866
(From JEDEC Board Ballot, JCB-10-12 and JCB-11-95, formulated under the cognizance of the
JC-42.3 Subcommittee on Volatile RAM.)
1 Scope
The JESD79-3 document defines DDR3L SDRAM, including features, functionalities, AC and DC
characteristics, packages, and ball/signal assignments with the exception of what is stated within
this standard.
The purpose of this standard is to define the DDR3L specifications that supersede the DDR3
specifications as defined in JESD79-3. The use of DDR3-800, DDR3-1066, DDR3-1333,
DDR3-1600, and DDR3-1866 titles in JESD79-3 are to be interpreted as DDR3L-800,
DDR3L-1066, DDR3L-1333, DDR3L-1600,and DDR3L-1866, respectively, when applying towards
DDR3L definition; unless specifically stated otherwise.
2 DDR3L VDD/VDDQ requirements
NOTE 1 Maximum DC value may not be greater than 1.425V. The DC value is the linear average of V
DD

DDQ
(t) over a
very long period of time (e.g., 1 sec).
NOTE 2 If maximum limit is exceeded, input levels shall be governed by DDR3 specifications.
NOTE 3 Under these supply voltages, the device operates to this DDR3L specifcation.
NOTE 4 Once initialized for DDR3L operation, DDR3 operation may only be used if the device is in reset while V
DD and
VDDQ are changed for DDR3 operation (see Figure 1).
