RAM

This is the “normal” type of memory associated with a computer system. The most part of a computer’s memory is random access memory (RAM). Which is in the form of silicon chips? Program and data are always loaded into this memory. Random access memory is one in which the contents can always be overwritten. Secondly, the access memory time of any memory location is independent of the location address.

Ram

This form of memory is also called semiconductor memory because it is made from semiconductor material. A semi conductor material is one which is used to make transistors and integrated circuits. One of such material is one which is used to make transistors and integrated circuits. One of such material is commonly used is silicon. This type of memory provides increased storage capacity and low access time. Each location of ram is individually numbered called address. 

Ram is mounted on the same board along with the CPU. Program instruction and data values are loaded in RAM. So if a computer has 64K memory, it will have 64 x 1024addressable locations. The data items stored in each location will be 32 bit and the address of each location will be 16 bit or 4 hexadecimal digits. Referring to our discussion of MAR and MBR in the previous section, the contents of MAR will be 16 bits and that of MBR will be 32 bits.

Ram is of two types:

1.   Dynamic RAM

The dynamic RAM used integrated circuits to store and read electric charges in the memory units. In smaller and slower microcomputers, it does not create any problem. However, the speed of operation of such a RAM is half the speed of faster computers, which certainly creates problems.

2.   Static RAM

        The static RAM is also designed that the electric charges do not read to be reinforces. The static RAM is up to ten times faster than dynamic RAM and is also more expensive.
