Definition of RAM (Random Access Memory)
RAM (Random Access Memory) is a type of content retrievable storage of a computer that is accessible within a fixed time does not care where the data is within the memory. This contrasts with sequential memory devices such as magnetic tape, disk and drum, in which the mechanical movement of the storage media dr force the computer to access the data sequentially.

- A history of RAM
A. RAM
RAM was invented by Robert Dennard and produced on a large - scale by Intel in 1968, long before the PC was invented by IBM pd year 1981. From this stems the development of RAM. At the beginning of creation, the RAM requires a voltage of 5.0 volts to run at a frequency of 4.77 MHz, the memory access time (access time) of about 200ns (1ns = 10-9 sec).
2. DRAM
In 1970, IBM created a labeled DRAM memory. DRAM has a working frequency of which varies from 4.77 MHz to 40MHz.
3. FP RAM
Fast Page Mode DRAM FPM DRAM or shortened to be found around the year 1987. This type of direct memory dominate the memory marketing, and people often refer to this type of memory "DRAM" alone, without naming the FPM. This type of memory works like an index or table of contents. The meaning is itself a part of which the memory address contained in a row.
4. EDO RAM
In 1995, were created the kind of memory (EDO DRAM) which is a refinement of the FPM. EDO memory read cycle dpt shorten it so that it can improve performance about 20 percent. EDO has an access time is quite variable, which is about 70ns to 50ns and working at a frequency of 33MHz to 75MHz. Although EDO is an improvement of FPM, but both can not be installed simultaneously, because of differences in ability.
5. SDRAM PC66
At the turn of the year 1996 - 1997, Kingston to create a memory module which can work at a speed (frequency) the same bus / sync with a working frequency of the processor. That's why Kingston call this kind of memory Synchronous Dynamic Random Access Memory (SDRAM). SDRAM is then better known as the PC66 because it works on a 66MHz bus frequency. Unlike the previous type of memory that requires a fairly high working voltage, SDRAM only requires a voltage of 3.3 volts and has an access time of 10ns.
6. PC100 SDRAM
Lapse within a year after PC66 mass produced and used, Intel made a new standard type of memory which is the development of PC66 memory. This new standard created by Intel to balance the system with the system chipset i440BX Slot 1 Intel is also created. This chipset is designed to be able to work on a bus frequency of 100MHz. This chipset is well developed by Intel to be paired with the latest Intel Pentium II processor that works on a 100MHz bus. Because the bus system works at a frequency of 100MHz while Intel still wants to use SDRAM memory system, it is developing SDRAM memory that can work at 100MHz bus frequency. Like its predecessor PC66, SDRAM memory is then known as PC100.
7. DR DRAM
In 1999, Rambus memory system by creating a new architecture and a revolutionary, totally different from SDRAM.Oleh Rambus memory architecture, memory is called Direct Rambus Dynamic Random Access Memory. By simply using a voltage of 2.5 volts, RDRAM is working on a 800MHz system bus via a bus system called the Direct Rambus Channel, able to stream data at 1.6 GB / second of it! (1GB = 1000MB).
8. PC800 RDRAM
Rambus also developed other types of memory with a capacity equal to DRDRAM. The only difference lies in the necessary working voltage. If DRDRAM requires a voltage of 2.5 volts, the voltage of RDRAM PC800 work on 3.3 volts. The fate of RDRAM memory is almost the same as DRDRAM, less desirable, if not utilized by Intel.
Intel has managed to create a very high-speed processor requires a memory system that is able to keep up and work together well. SDRAM memory types is not worth it anymore. Intel needs more than that.
9. PC133 SDRAM
In addition to the development of PC800 RDRAM memory in 1999, SDRAM memory has not been abandoned, even by the Vikings, even more enhanced. As the name implies, PC133 SDRAM memory works at 133MHz bus frequency with an access time of 7.5 ns and is able to stream data at 1.06 GB per second. Although developed to work on the PC133 bus frequency of 133MHz and the memory is also capable of running at 100MHz bus frequency while ill as the capabilities of the PC100 at that frequency.
10. PC150 SDRAM
SDRAM memory development is increasingly becoming - so after Mushkin, in 2000 successfully developed a memory chip that can operate at a frequency of 150MHz bus, even though there has been no official standards regarding the rate and the system bus or chipset for this. Still a working voltage of 3.3 volts, PC150 memory has an access time of 7ns and able to stream data at 1.28 GB per second.
This memory is deliberately created for overclockers, but the game application users and 3 dimensional graphics, desktop publishing, and server computers can take advantage of the presence of PC150 memory.
11. DDR SDRAM
Still in 2000, successfully developed Crucial SDRAM memory capacity is doubled. If pd regular SDRAM can only run one instruction every one clock cycle bus frequency, the DDR SDRAM can execute two instructions in the same time. The technique used is to use the full one frequency. If the regular SDRAM only do the instructions on the positive wave, the DDR SDRAM running good instruction on the wave of positive and negative waves. Because of this memory is called DDR SDRAM which stands for Double Data Rate Synchronous Dynamic Random Access Memory.
12. DDR RAM
In 1999 two large companies microprocessor INTEL and AMD compete in the increase in CPU clock speed. But confronted with obstacles, because when increasing the memory bus to 133 Mhz Memory requirements (RAM) will be greater. And to resolve the issue then be made DDR RAM (double data rate transfers) that was originally used on the graphics card, because now you can use only 32 MB for 64 MB capacity. AMD is the first company to use DDR RAM on the motherboard.
13. DDR2 RAM
When the memory type DDR (Double Data Rate) perceived by the accelerating pace began to slow down the performance of the processor and graphics processor, DDR2 memory is the presence of logical advances in memory technology refers to the addition of speed and anticipation of the width of the access point triangle processor, memory, and graphics interface which is present computational speed with a double.
The main differences between DDR and DDR2 is the data rate and increased latency doubled. This change is intended to produce a maximum speed in an increasingly faster computing environment, both in terms of processor and graphics.
In addition, DDR2 voltage requirement also decreased. If the registered DDR voltage 2.5 Volt needs, the needs of DDR2 is only 1.8 volts.
14. DDR3 RAM
DDR3 RAM has a power requirement is reduced approximately 16% compared to DDR2. This is because DDR3 is already using 90 nm technology so that the required power consumption is only 1.5v, much less when compared to DDR2 and DDR 2.5V 1.8v. In theory, held by the RAM speed is quite stunning. He was able to transfer data with an effective clock of 800-1600 MHz. In the 400-800 MHz clock, much higher than DDR2 at 400-1066 MHz (200-533 MHz) and DDR for 200-600 MHz (100-300 MHz). The prototype of DDR3 has 240 pins.
