Introduction to RAM (Random Access Memory)?

RAM stands for Random Access Memory, main memory, primary memory, is a hardware device that allows information to stored and retrieve in the computer. The RAM memory is attached to the motherboard of the computer that is high speed device in the system that temporarily stores all information. RAM store information actively using so that is can be accessed quickly,

Type of RAM (Random Access Memory)?

There are two primary type of RAM (Random Access Memory).

Static Random Access Memory (SRAM): A fast memory technology that requires power to hold its content. that retains its state for data bits or holds data as long as it receives the power. Static RAM used for high speed registers,

Dynamic Random Access Memory (DRAM): It stores each bit of data on a small capacitor within the memory cell. The capacitor can be either charged or discharged and this provides the two states, “1” or “0” for the cell. This memory is located closer to your processor, too, so your computer can easily and quickly access it for all the processes you do. This captivator needs to be refreshed often otherwise information fades.

  • SDRAM (Synchronous Dynamic RAM):
  • RDRAM (Rambus Dynamic RAM)
  • DDR SDRAM (Double Data Rate Synchronous Dynamic RAM): Synchronous dynamic random access memory is any DRAM where the operation of its external pin interface is coordinated by an externally supplied clock signal. This makes it easy to manage faster, and the speed of the SDRAM measured in MHz instead of nanoseconds. It most widely used in computers. Nowadays it is also used in other systems.
