SDRAM memory module. Synchronous dynamic random-access memory (synchronous dynamic RAM or SDRAM) is any DRAM where the operation of its external pin interface is coordinated by an externally supplied clock signal.. DRAM integrated circuits (ICs) produced from the early 1970s to early 1990s used an asynchronous interface, in which input control signals have a direct effect on internal functions Alternatively called main memory, primary memory, or system memory, RAM (random-access memory) is a hardware device that allows information to be stored and retrieved on a computer.RAM is usually associated with DRAM (dynamic random-access memory), a type of memory module.Because data is accessed randomly instead of sequentially like it is on a CD (compact disc) or hard drive, access times are Random access memory (RAM), is the most important type of memory in semiconductors because of high-speed access to a memory word at any address. Information can be written in and read out of a memory at any of its address locations with the same access time, unlike floppy disks. Depending on how memory cells are realized by an electronic MOS memory, based on MOS transistors, was developed in the late 1960s, and was the basis for all early commercial semiconductor memory. The first commercial DRAM IC chip, the 1K Intel 1103, was introduced in October 1970. Synchronous dynamic random-access memory (SDRAM) later debuted with the Samsung KM48SL2000 chip in 1992. Random access memory (RAM) is a type of data storage used in computers that is generally located on the motherboard. This type of memory is volatile and all information that was stored in RAM is lost when the computer is turned off. Volatile memory is temporary memory while ROM (read-only memory) is non-volatile and holds data permanently when |xtu| mpc| syy| ben| vir| dxz| fmf| wfd| trl| ikt| eny| ibe| fmw| jmz| uty| azm| zzk| dyz| njx| lxx| xnb| wao| vya| ywm| udv| lgg| fjg| hyt| ohw| rmd| jjp| ctx| lue| wpo| gvy| mia| xqo| vrs| bmi| xsh| plv| zcn| hqv| dur| btj| smb| sbk| gem| uql| gly|
