THE TYPES OF RAM (Random Access Memory)

below are the types of RAM

RAM (Random-Access Memory)
It is a comprehensive term for all the memories that can be read or written is not all (non-linear). However he was referring specifically to the memory chip is based on when all is based on chip memory. RAM is a bit different with the ROM, because computers can only read the ROM, but can read and write to RAM.

SIMMs (Single In-line Memory Module) and DIMM (Dual In-line Memory Module)
SIMM and DIMM are not referring to the types of memory but refers to the module (board circuits which along with the chip) in which the RAM is applied together. SIMM is a module that among the examined earlier by offering as much as 32​​-bit data. Due to Pentium processors have been engineered to handle the data among the examined wider than that, SIMMs must be used in pairs with the main board Pentium. However SIMM still may be used singly, but only on the main board which is based processors processors 486 or more slowly.
When the DIMM is the newest module will offer among the examined 64-bit to make it more suitable for use with Pentium processors and the latest processors such as AMG and Cyrix. In terms of the purchase of memory components, each unit DIMM evident attempt to control work that may be carried out by two units of SIMM. Additionally it may be used singly on the main board Pentium. In terms of long-term DIMM is also more economical because it does not need to add one more DIMM computer memory systems.


DRAM (Dynamic RAM)
Also represents a type of DRAM main memory in computers today and he will be referred if you want to tell someone that free your PC has 32MB of RAM. In the DRAM, intimation will be stored as a feature of the electronic charge in a capacitor. In every millisecond of electronic charge in the DRAM capacitor will discharge the original and need to be refreshed (refresh) to perpetuate its value. A continual refreshment has become a reason to put the term dynamic in the presence of the composition of letters of RAM.

SDRAM (Synchronous Dynamic RAM)
There are two advantages contained in the type of SDRAM memory chips. First, he can control the bass so that the 100 Mhz decency and second, the type of SDRAM memory chips may be connected (synchronized) with the system clock itself. Contained in the chip technology allows two memory pages opened by continual.
When memory chips is a replication type SLDRAM SDRAM chip type which has improved the technology by offering a higher appropriateness bass and he used a small pallets of data to control the requested address; installation and direction to the DRAM memory chips. SLDRAM election involves only low cost but offered memory performance is higher.


VRAM (Video RAM)
VRAM type memory chips work well on video performance and is allowed to see him on KAD video accelerator or on the main board which has the video technology. VRAM chips are usually used to store the content of pixels for an exposure chart.
The use VRAM chips will provide a decent video performance and seeks to reduce pressure on the CPU. VRAM chips involves the use of two access ports to the memory cell and one thereof is used constantly to refresh the exposure and the other one is used to convert the data to be presented. The use of two ports can provide an appropriate video offerings compared with the use of DRAM chips and SRAM chips that have only one access port.
