RAM

RAM

This is same as the main memory which used by it self. The Random Access Memory reference to read and write that is read, most RAM is volatile which means that it required to flow of electricity to means as soon as the power is turned off whatever data was in RAM his lost.

• RAM is volatile.
• As soon as the machine is switched off, data and information is erased.

There are two types of RAM.

SRAM (Static Random Access Memory)

DRAM (Dynamic Random Access Memory)

SRAM (Static RAM)

Static Random Access Memory (SRAM) is a type of RAM that holds data and information in a static form. State RAM chips use a matrix of 6-transistors and no-capacitors. SRAM is thus used as Cache Memory and has fast access.

Character of Static RAM (SRAM)

• Long data life
• Expensive
• Faster
• Cache Memory
• Low power consumption
• No need to refresh
• Large size

DRAM (Dynamic RAM)

Dynamic Random Access Memory is a type of RAM, must be continuously refreshed in order to maintain the data and information. Each memory cell in a dynamic RAM is made of only one transistor and system memories as it is cheap and small. All Dynamic RAMs are made up of memory cells.

Character of Dynamic RAM (DRAM)

• Short data life
• Less expensive
• Slower
• Main Memory
• High power consumption
• Need to be refreshed continuously
• Smaller size

There are three types of Dynamic RAM (DRAM)

• SDRAM
• RDRAM
• DDR RAM

SDRAM

The two types of RAM. Dynamic RAM and static RAM to be referenced where as static RAM needs to be not rephrased.
      RAM are volatile means that they lost there contents when the computer is turned off.
