SUMMARY OF MEMORY

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.
