What is a RAM

Random-access memory (RAM) is a form of computer data storage.Random access memory (RAM) is the best known form of computer memory.

How RAM works

RAM is considered "random access" because you can access any memory cell directly if you know the row and column that intersect at that cell.

Types of RAM

SRAM: Static random access memory uses multiple transistors, typically four to six, for each memory cell but doesn't have a capacitor in each cell. It is used primarily for cache.

DRAM: Dynamic random access memory has memory cells with a paired transistor and capacitor requiring constant refreshing.

  • EDO DRAM: Extended data-out dynamic random access memory does not wait for all of the processing of the first bit before continuing to the next one.
  • SDRAM: Synchronous dynamic random access memory takes advantage of the burst mode concept to greatly improve performance.
  • DDR SDRAM: Double data rate synchronous dynamic RAM is just like SDRAM except that is has higher bandwidth, meaning greater speed.
  • RDRAM: Rambus dynamic random access memory is a radical departure from the previous DRAM architecture. Designed by Rambus, RDRAM uses a Rambus in-line memory module (RIMM), which is similar in size and pin configuration to a standard DIMM.
