Ram ( Random Access memory)

RAM ( Random Access memory)

Ram (pronounced ramm) stand for Random Access memory

RAM is the most common type of memory found in computers and other devices, such as printers

The primary function of Ram provide a temporary storage.
Place for information about devices and application.Ram chip is "VOLATILE" meaning without power can be store data.


Random access memory (RAM) is the best known form of computer memory. RAM is considered "random access" because you can access any memory cell directly if you know the row and column that intersect at that cell.

memory chip is an integrated circuit (IC) made of millions of transistors and capacitors. In the most common form of computer memory, dynamic random access memory (DRAM), a transistor and a capacitor are paired to create a memory cell, which represents a single bit of data. The capacitor holds the bit of information -- a 0 or a 1 (see How Bits and Bytes Work for information on bits)

DRAM  DRAM (pronounced dee-ram) to distinguish it from static RAM (SRAM). Static RAM is faster and less volatile than dynamic RAM, but it requires more power and is more expensive.
DRAM connectivity on DIPP (DUAL IN LINE PACKAGE) use 8086 to 8088,and speed is 16kb to 256kb.

EDO (Extended Data Out RAM) connectivity on SIMM (Single In-line Memory Module).EDO Ram use in 286 to p1..
their are two type of edo ram
1:contain 1 to 30 pins and 4 chip maximum cache 2MB
2:contain 1 to 72 pins and 8 chip maximum cache 8MB.

Synchronous dynamic random access memory (SDRAM)

Synchronous dynamic random access memory (SDRAM) is dynamic random access memory (DRAM) that
SD RAM (Synchronous dynamic random access memory) connectivity on DIMM(DUAL IN LINE MEMMORY MODULE) use in p2 to p3.Contain 168 pins and clip holding.

is synchronized with the system bus.






RD ram (ROMBUS DYNAMIC)
only use in p4 starting, 800 bus speed 1.66ghz.RD-RAM connectivity on RIMM (Rambus in-line memory module).it connect on pair from that's why it is remove,it not connect in single form.

Double data rate synchronous dynamic random-access memory (DDR SDRAM)
use complete in p4 233to 33mhz contain 1 to 184  pin and having cut on starting 512mb to 2gb.

DDR2
1gb to 4gb 333 to 8000 bus speed use in Dual core and Quad core .it contain 1 to 248 pins and cut at center(mid Cut).


DDR3

433 to 1.6ghz use in core i2 ,i5 and i7.it contain 1 to 204 pins and at end cut(3rd quarter cut)
