TYPES OF RAM

• SIMMS
• DIMMS
• 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

4
DIMM

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

5
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.

6
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.

7
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."

8
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

9
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.
