Ram Overview:
Ram stands for Random Access Memory. It gets the
word “random” because information can be accessed
in non-sequential order. Though the data itself is
stored together, it could be anywhere in the
“container” or amount of Ram available. RAM is
measured in “bits”, and 8 bits equals 1 byte. A
kilobyte equals 1024 bits and a megabyte equals
1024 kilobytes.
SRAM(Static Ram)
Static RAM is a type of RAM that holds its data
without external refresh, for as long as power is
supplied to the circuit. This is contrasted to dynamic
RAM (DRAM), which must be refreshed many times
per second in order to hold its data contents. SRAMs
are used for specific applications within the PC,
where their strengths outweigh their weaknesses
compared to DRAM.
SRAM(Static Ram)
 Simplicity: SRAMs don’t require external refresh circuitry or
other work in order for them to keep their data intact
 Speed: SRAM is faster than DRAM
 Compared to DRAM, SRAM is more power- efficient when
idle
 SRAM is several times more expensive than DRAM
DRAM (Dynamic Ram)
 Dynamic RAM is the standard computer memory of
the vast majority of modern desktop computers. It is
a volatile memory that needs to be refreshed with
voltage regularly, otherwise it loses the information
stored on it. Dynamic RAM is also referred to as
DRAM. Volatile means that it loses the information
stored on it as soon as power is withdrawn.
DRAM (Dynamic Ram)
 Dynamic RAM is referred to by its size and speed. For
example, the packaging or description of the memory module
might list 1066 Mhz 1 Gb DRAM. The 1066 Mhz is the speed
at which a computer can read and write to the memory, and
the higher number the better. The 1 Gb is the usable space on
the chip; in this example, the chip can store 1 gigabyte of
information on it while it has power.
 Example of DRAM is DIMM, SO-DIMM and DDR Memory
Sticks.
Types of RAM Memory Module:
1.SIMM Memory
Computer memory has a big effect on system
performance. Pictured above is SIMM
memory, or single in-line memory module,
which is a type of RAM memory module.
2.DIMM Memory:
DIMM, or dual in-line memory module, has a
64-bit path to memory chips, whereas the
has only a 32-bit.
3.SO-DIMM Memory:
SO-DIMM, or small outline dual in-line memory
module, is made with integrated circuits and is
about half the size of DIMM modules
