There are two basic types of RAM: Dynamic RAM (DRAM) and Static RAM (SRAM). Dynamic RAM is the more common and needs to refreshed thousands of times per second. Static RAM does not need to be refreshed making a lot faster but also much more expensive.

2. TYPES OF RAM
There are two basic types of RAM: Dynamic
RAM (DRAM) and Static RAM (SRAM).
 Dynamic RAM is the more common and
needs to refreshed thousands of times per
second.
 Static RAM does not need to be refreshed
making a lot faster but also much more
expensive.

3. SIZES OF RAM
RAM is measured by its speed (MHz) and by
its size (megabytes or gigabytes).
• For example you could have DDR RAM
(name) 400mhz (speed of the RAM) 256mb
(RAM size). The most common RAM sizes
are, 512mb, 1Gb, 4Gb and 8Gb.

4. HOW RAM WORKS?
• Operating systems, application programs
such as Microsoft word, Firefox or a game
program are kept in the RAM so as to be
quickly accessed by the CPU.
• Computer RAM is much faster then other
storage devices but it will lose all its
information when the computer is switched
off.

5. LATEST AVAILABLE RAM
Graphics Double Data Rate Synchronous Dynamic RAM (GDDR
SDRAM)
Popular Products Using GDDR SDRAM: Video graphics cards,
some tablets
• GDDR SDRAM is a type of DDR SDRAM that is
specifically designed for video graphics rendering,
typically in conjunction with a dedicated GPU (graphics
processing unit) on a video card.

6. UPCOMING LATEST RAMS
Double Data Rate 5 Synchronous Dynamic Random-Access
Memory,
officially abbreviated as DDR5 SDRAM. DDR5 is
planned to reduce power consumption once again,
while doubling bandwidth and capacity relative
to DDR4 SDRAM.
• As of February 2019 the standard is still being
finalized; however, some companies are planning
to bring the first products to market by the end of
2019.
