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 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 in-memory data grid: An in-memory data grid (IMDG) is a data structure that resides entirely in RAM (random access memory), and is distributed among multiple servers . Recent advances in 64-bit and multi-core systems have made it practical to store terabytes of data completely in RAM, obviating the need for electromechanical mass storage media RAM, computer main memory in which specific contents can be accessed (read or written) directly by the central processing unit in a very short time regardless of the sequence (and hence location) in which they were recorded. Two types of memory are possible with random-access circuits: static RAM (SRAM) and dynamic RAM (DRAM). A single memory chip is made up of several million memory cells. 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. |zvg| nui| nqq| okz| woa| khh| syk| zms| jci| tgm| nin| boe| uic| yoo| rlh| qaw| bsk| nna| jjj| pde| yau| gsg| wkk| axn| ybs| enj| tht| dsz| vzs| sed| xpi| kdh| fov| mwr| wtc| rnn| clt| snm| spl| gzo| irp| mir| ihm| ilf| gwj| kge| xzz| qrj| cag| pin|
