RAM (Random Access Memory)

We can Categorize Memory Device as Primary Memory and Secondary Memory. RAM and ROM are example for primary memory and Hard Dick, Floppy Dick, CD and DVD are example for Secondary Memory.The Purpose of RAM is store data for temporarily. We plug this RAM to RAM Slot in the Motherboard.

Dynamic RAM

Dynamic RAM price is lower more than Static RAM. Can, Store Data for short time.  Data is alway update, when data strong long time. Data can bee erase when stop updating data or stop current supply.

Static Memory

Static RAM are high on price ore than Dynamic RAM and static RAM are speed more than Daynamic RAM. Can store data for long time without updating data and need current supply for store data. Static RAM are use for Cache Memory.

"3101" RAM is a first RAM, it was introduced on 1969. 64bit is a capacity of this RAM.this RAM was created in Static RAM technology. 1102 and 1103 RAM was creted on 1970-1971. it was a Dynamic RAM. 1103 was has a 1kb capacity.

Non Using,Old RAM Modules.

These RAM Modules are can't use with new softwares. New applications can't run with old RAM. Because they are not using today.

• DIP CHIP

These chips have 16 pins. These chips need big area in motherboard. because these chips need to plug other by other.

• 30 PIN SIPP

This 30 PIN SIPP module was introduced after dDIP Chips.  This was 30 pin SIPP introduced on 1980.  THIS SIPP(single inline plastic package) was need plug to 30 pin slot in the motherboard.

• 30 PIN SIMM

This 30 pin SIMM was introduced with 256MB, 1GB, 2GB, 4GB, 8GB and 16GB speeds. This SIMM(Single In-Line Memory Module) was introduced for 386 and 486 motherboards.

• 72 PIN SIMM

This SIMM have 72 pins. This was introduced for 486 and Pentium motherboards and this was introduced with, 1MB, 2MB,4MB, 8MB, 16MB,.32MB AND 128MB speeds.

Old RAM Modules

These follower modules are used in Pentium 2,3,4 and old AMD modules. But we can't buy these RAM Modules in today shops. Following informations are about old RAM modules.

• DIMM Module

However DIMM (dual in-line memory modules) are using today new computers.  These RAM Modules is 5.25 inch in width. This RAM Modules was alway used in Pentium 2 and Pentium 3 computers.

• DDR Module

This was introduced for Pentium IV computers and this was match for AMD RAM Modules. This was introduced in 32MB, 64MB, 128MB, 256, 512MB and 1GB speeds.

New RAM Modules

• DDR2

DDR2 and DDR3 RAM modules are very famous RAM modules. but DDR2 is now removing form useing. This was alway used in Pentium IV computes and also this is used in Intel Core 2 Duo, Intel Core 2 Qued. DDR2 modules are have new AMD motherboards and this was can buy in 256MB, 512MB and 1GB in speeds.

• DDR3

 This was introduced 1GB, 2GB and4GB speeds. However we can't plug DDR3 RAM to DRR2 Slot or DDR2 to DDR3 slot.

Alway, we can see two RAM slot in new Motherboards. but some peoples are plug two 4GB RAM to Windows 7 32 bit Computes. But Windows 7 32bit can to get only 3GB RAM. Windows 7 can't get more than 3GB,  But we can use ultimate RAM Speeds with Windows 7 64 Bit Operating System and with  Windows 8 operating system.
