RAM - DDR3

DDRx type memories are most often used as operational memory of personal computers. The original DDR SDRAM (short for double-data-rate synchronous dynamic random access memory) is sometimes retrospectively referred to as DDR1; with further development other types have been developed, referred to as DDR2, DDR3, DDR3, DDR4, DDR5.

DDR3 or double-data-rate 3 SDRAM is the evolutionary successor to DDR2 RAM. This technology is used for high-speed storage of work data. The main difference between DDR2 and DDR3 is in memory speed. The number of operations per second increased from 400 million to 1.2 billion for DDR2 to 800 million to 2.4 billion for DDR3.

DDR memory modules have 184 pins and a lock that ensures proper installation in the memory slot on the motherboard. These modules are not compatible with older SDRAM slots (they only have 168 pins), nor with newer DDR2 and DDR3 slots (240 pins).

The successor to DDR3 and one of the last variants of DRAM, which have been used since 1970, is DDR4 RAM, which appeared on the market in 2014.
