RAM (Random Access Memory)

RAM stands for random access memory. This is where a PC stores before its processed. RAM is form of volatile memory, which means that it only holds onto data work the chip is powered and erases everything when you shut down the PC. RAM memory is measured in gigabytes(GB).

It is also called read-write memory or the main memory or the primary memory. The programs and data that the CPU requires during the execution of a program are stored in this memory. It is a volatile memory as the data lost when the power is turned off.

Two main types of RAM are:

·         Static RAM

·         Dynamic RAM

 

     1.   Static RAM

Static RAM is the full form of SRAM. In this type of RAM, data is stored using the state of a six transistor memory cell. Static RAM is mostly used as a cache memory for the processor (CPU).

     2.   Dynamic RAM

DRAM stands for Dynamic Random Access Memory. It is a type of RAM which allows you to stores each bit of data in a separate capacitor within a specific integrated circuit. Dynamic RAM is a standard computer memory of the many modern desktop computers.

This type of RAM is a volatile memory that needs to be refreshed with voltage regularly.
