3、ility andimprovement of products, and assisting the purchaser in selecting and obtaining with minimumdelay the proper product for use by those other than JEDEC members, whether the standard is tobe used either domestically or internationally.JEDEC standards and publications are adopted without regar
4、d to whether or not their adoptionmay involve patents or articles, materials, or processes. By such action JEDEC does not assumeany liability to any patent owner, nor does it assume any obligation whatever to parties adoptingthe JEDEC standards or publications.The information included in JEDEC stand
5、ards and publications represents a sound approach toproduct specification and application, principally from the solid state device manufacturerviewpoint. Within the JEDEC organization there are procedures whereby a JEDEC standard orpublication may be further processed and ultimately become an ANSI s

10、 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 ScopeThe JESD79-3 document defines DDR3L SDRAM, including features, functionalities, AC and DC characteristics, packages, and ball/signal assignments with
11、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 DDR3
12、L-800, DDR3L-1066, DDR3L-1333, DDR3L-1600,and DDR3L-1866, respectively, when applying towards DDR3L definition; unless specifically stated otherwise.2 DDR3L VDD/VDDQ requirementsNOTE 1 Maximum DC value may not be greater than 1.425V. The DC value is the linear average of VDD/VDDQ(t) over a very long
13、 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
14、 reset while VDD and VDDQ are changed for DDR3 operation (see Figure 1).Table 1 Input/output functional descriptionSymbol Type FunctionVDDSupply Power Supply: DDR3L operation = 1.283 V to 1.45 V; DDR3 operation = 1.425 V to 1.575 VVDDQSupply DQ Power Supply: DDR3L operation = 1.283 V to 1.45 V; DDR3
