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 ...
None of its successors are forward or backward compatible with DDR1 SDRAM, meaning DDR2, DDR3, DDR4 and DDR5 memory modules will not work on DDR1-equipped motherboards, and vice versa. Compared to single data rate ( SDR ) SDRAM, the DDR SDRAM interface makes higher transfer rates possible through more strict control of the timing of the ...
The UniDIMM specification was created by Intel for its Skylake microarchitecture, whose integrated memory controller (IMC) supports both DDR3 (more specifically, the DDR3L low-voltage variant) and DDR4 memory technologies. [2] [3] [4]
FPM, EDO, SDR, and RDRAM memory was not commonly installed in a dual-channel configuration. DDR and DDR2 memory is usually installed in single- or dual-channel configuration. DDR3 memory is installed in single-, dual-, tri-, and quad-channel configurations. Bit rates of multi-channel configurations are the product of the module bit-rate (given ...
DDR3 memory support [ edit ] Intel officially states [ 8 ] [ 9 ] that Skylake's and Kaby Lake's integrated memory controllers (IMC) support DDR3L memory modules only rated at 1.35 V and DDR4 at 1.2 V, which led to the speculation that higher voltages of DDR3 modules could damage or destroy the IMC and processor.

A memory rank is a set of DRAM chips connected to the same chip select, which are therefore accessed simultaneously. In practice all DRAM chips share all of the other command and control signals, and only the chip select pins for each rank are separate (the data pins are shared across ranks).
The documentation of modern memory modules, such as the standards for the memory ICs [8] and a reference design of the module [9] requires over one hundred pages. The standards specify the physical and electrical characteristics of the modules, and include the data for computer simulations of the memory module operating in a system. [10]
