RAM PROPERTIES
Friends in the last post
i tried to explain the different types of ram as well as given the details of
its similarities now i am going to show you how the properties of ram can be
judged .
SO LET US BEGIN.
SINGLE SIDED VS DOUBLE SIDED
DIMMS or DUAL INLINE
MEMORY MODULE whatever you call are often referred to as single chip or double
sided to describe whether the chips are located on one or both of the modules
printed circuit board .
However these terms may
cause confusion or distract you from the topic, as the physical layout of the
chips does not necessarily relate to how they are logically organized or
accessed in whatever terms you are told.
ERROR CORECTING CODE MEMORY (ECC MEMORY)
An ERROR CORRECTING CODE (or ECC) whatever
general public says could be a kind of computer data
storage which will detect and proper the more
common types of internal data
corruption in simple words with firmness and boldness.
Most computers or workstations use ECC where data corruption of knowledge or misspelt
or mislead data can't be tolerated
under any circumstances or in any mislead cannot be tolerated during this way like for
scientific or financial computing in firm terms.
Error correcting code (ECC) memory is commonly seen in high
end motherboards or firms that use ECC memory that provide important services
or software functions. Unlike normal parity memory, ECC memory can find and fix
errors, i'm saying these items in generalized
manner.ECC memory generally
costs more, so usually see motherboard designed for ECC memory when there as a
specific need .
ECC memory maintains a
memory system effectively free from single bit errors, usually it does in this
way to prevent redundancy. The data i.e.
Read from each word is always the same as the data that had been written to it,
even if the single bit is actually
stored or more in some cases has been to the wrong state.
The ECC memory is employed where the info must be very
accurate and also the memory is
required to possess a correcting
capability.
It adds cost to the memory module and employed in server level
computers where the info accuracy is incredibly important
some non ECC memory with parity support allows errors to be detected but not
corrected otherwise errors which will occur don't seem to be detected now
which is why it's on the demand
in markets.
Now we are visiting speak about memory
modules. So let s begin
SINGLE INLINE
MEMORY MODULE
A SIMM or one inline memory
module may be a form of memory module
containing random access memory employed in computers
from the first 1980 s to the
late 1990 s and it had been in pretty much demand.
It differ from dual inline memory module the foremost predominant type of memory module
today therein the contacts
on a SIMM or redundant on each side of the module.
DUAL INLINE MEMORY
MODULE
A DIMM or dual inline memory module comprises a series of
dynamic random access memory integrated circuits. These modules are printed on computer circuit boards and
designed to be used in personal
computers, workstations, and servers.
DIMMS began to exchange SIMMs because the predominant form of memory module because the intel p5
based pentium processors to achieve market share.
While the contact on SIMMs on each side are
redundants , DIMMS have separate electrical contacts on each sides of the
module.
Another different is that standard SIMMs have 32 bit data
path, while standard DIMMS have 64 bit data path.
