SDRAM history Synchronous dynamic random-access memory

eight sdram ics on pc100 dimm package.

although concept of synchronous dram understood 1970s , used intel processors, in 1993 sdram began path universal acceptance in electronics industry. in 1993, samsung introduced km48sl2000 synchronous dram, , 2000, sdram had replaced virtually other types of dram in modern computers, because of greater performance.

sdram latency not inherently lower (faster) asynchronous dram. indeed, sdram slower contemporaneous burst edo dram due additional logic. benefits of sdram s internal buffering come ability interleave operations multiple banks of memory, thereby increasing effective bandwidth.

today, virtually sdram manufactured in compliance standards established jedec, electronics industry association adopts open standards facilitate interoperability of electronic components. jedec formally adopted first sdram standard in 1993 , subsequently adopted other sdram standards, including ddr, ddr2 , ddr3 sdram.

sdram available in registered varieties, systems require greater scalability such servers , workstations.

today, world s largest manufacturers of sdram include: samsung electronics, panasonic, micron technology, , hynix.
