The DDR3L ( DDR3 Low Voltage) standard is an addendum to the JESD79-3 DDR3 Memory Device Standard specifying low voltage devices. [31] The DDR3L standard is 1.35V and has the label PC3L for its modules. Examples include DDR3L‐800 (PC3L-6400), DDR3L‐1066 (PC3L-8500), DDR3L‐1333 (PC3L-10600), and DDR3L‐1600 (PC3L-12800). Memory specified to DDR3L and DDR3U specifications is compatible with the original DDR3 standard, and can run at either the lower voltage or at 1.50 V. [32] However, devices that require DDR3L explicitly, which operate at 1.35V, such as systems using mobile versions of fourth-generation Intel Core processors, are not compatible with 1.50V DDR3 memory. [33] DDR3L is different from and incompatible with the LPDDR3 mobile memory standard. Addendum No. 2 to JESD79-3, 1.25 V DDR3U-800, DDR3U-1066, DDR3U-1333, and DDR3U-1600". October 2011 .

DDR2 speeds

DDR3-xxx denotes data transfer rate, and describes DDR chips, whereas PC3-xxxx denotes theoretical bandwidth (with the last two digits truncated), and is used to describe assembled DIMMs. Bandwidth is calculated by taking transfers per second and multiplying by eight. This is because DDR3 memory modules transfer data on a bus that is 64 data bits wide, and since a byte comprises 8 bits, this equates to 8 bytes of data per transfer. In February 2005, Samsung introduced the first prototype DDR3 memory chip. Samsung played a major role in the development and standardisation of DDR3. [2] [3] In May 2005, Desi Rhoden, chairman of the JEDEC committee, stated that DDR3 had been under development for "about 3 years". [4] Another benefit is its prefetch buffer, which is 8-burst-deep. In contrast, the prefetch buffer of DDR2 is 4-burst-deep, and the prefetch buffer of DDR is 2-burst-deep. This advantage is an enabling technology in DDR3's transfer speed.

Some manufacturers further propose using "dual-gate" transistors to reduce leakage of current.

"Pipe Dreams: Six P35-DDR3 Motherboards Compared". Tom's Hardware.Non-registered (a.k.a. " unbuffered") RAM may be identified by an additional U in the designation. [30]

Fully buffered modules, which are designated by F or FB and do not have the same notch position as other classes. Fully buffered modules cannot be used with motherboards that are made for registered modules, and the different notch position physically prevents their insertion. DDR3 does use the same electric signaling standard as DDR and DDR2, Stub Series Terminated Logic, albeit at different timings and voltages. Specifically, DDR3 uses SSTL_15. [13]
