Double Data Rate 3 Synchronous Dynamic Random-Access Memory (DDR3) SDRAM is a common type of volatile semiconductor memory. The DDR double data rate technology transfers data twice per clock cycle, doubling the transfer rate of previous sync DRAM devices. The DDR3 version, first introduced in 2005 and widely adopted in 2007, provided performance enhancements and lower power consumption than the earlier DDR and DDR2 versions.

As technology marches forward, there is an increase in the execution of data. Although mature microprocessing technologies, such as NXP's iMX6, QorIQ, and PowerQUICC-III, can still manage throughput, DRAM capacity limitations may pose a challenge.

Upon introduction, DDR3 memory offered capacities of 1 and 2 GB, eventually advancing to 4 GB. Since then, Intelligent Memory, Integrated Silicon Solution (ISSI), and other leading broad-use memory suppliers recognized the need for increased capacities, and now offer 8 GB and 16 GB densities. These additions allow applications to maintain existing processor designs and avoid redesigns due to DRAM capacity limitations.

The goal of extending design life aligns with Rochester Electronics’ commitment to providing authorized distribution and licensed manufacturing solutions for obsolete and end-of-life components.
