TYPES OF RAM

SIMM’S DIMM’S DRAM SDRAM RDAM VDRAM

SIMMS RAM

Single Inline Memory Module. A high-density DRAM package alternative consisting of several components connected to a single printed circuit board. SIMMs are small memory cards with data buses of 32, 36, or 40 bits. SIMMs have functionally equivalent connections on both sides of the card. Designed to meet JEDEC standards, SIMMs come with a variety of sizes, speeds, and features

DIMM

Dual inline memory module. A module with signal and power pins on both sides of the board (front and back).

SRAM

Acronym for Static Random Access Memory which is an integrated circuit similar to a DRAM (dynamic random access memory) with the exception that the memory does not need to be refreshed. Unlike volatile memory (DRAM), SRAM retains its contents even when the main current is turned off.

DRAM

Dynamic random access memory. A type of memory component used to store information in a computer system. "Dynamic" means the DRAMs need a constant "refresh" (pulse of current through all of the memory cells) to keep the stored information.

SDRAM

Synchronous Dynamic Random Access Memory or Synchronous DRAM.

A DRAM designed to deliver bursts of data at very high speed using automatic addressing, multiple page interleaving, and a synchronous (or clocked) interface.

Precisely it is SDR SDRAM (single data rate SDRAM) but is usually referred to as just "SDRAM."

RDRAM

Rambus DRAM is a revolutionary type of DRAM that uses a 16-18 bit data path and is designed to operate with Front Side Bus speed of 800MHz, producing a burst transfer rate of 1.6 gigahertz

VIDEO DRAM

Video RAM. DRAM with built in serial register/access memory designed for video applications transfers data to and from the graphics controller.

How Much Ram Is Needed?

To run a desktop computer with a Pentium 4 processor running Windows XP I would recommend 300 MB of Ram to provide adequate memory for the processors speed.
