Which one of the following statement is correct?a)PROM contains a prog...
Correct Statement: PROM contains a fixed AND array and a programmable OR array.
Explanation:
PROM stands for Programmable Read-Only Memory. It is a type of non-volatile memory that is programmed only once by the manufacturer or the user. The data stored in the PROM can be read as many times as required, but it cannot be modified or erased.
PROM consists of two main parts:
1. Fixed AND Array: It is a matrix of diodes or transistors that are permanently connected to the address inputs of the PROM. The fixed AND array generates a set of product terms based on the input address. These product terms are used to select the specific memory location that stores the desired data.
2. Programmable OR Array: It is a matrix of fusible links or antifuses that are connected to the output of the fixed AND array. The programmable OR array allows the user to program the desired data by selectively blowing the fuses or creating antifuses. Once programmed, the data is stored permanently in the PROM.
Advantages of PROM:
1. Low cost
2. High reliability
3. High speed
4. Non-volatile memory
Disadvantages of PROM:
1. Limited flexibility
2. Cannot be reprogrammed
3. High programming cost
4. Limited storage capacity
Conclusion:
PROM is a type of non-volatile memory that is programmed only once by the manufacturer or the user. It consists of a fixed AND array and a programmable OR array. The fixed AND array generates a set of product terms based on the input address, while the programmable OR array allows the user to program the desired data. PROM has advantages such as low cost, high reliability, high speed, and non-volatile memory, but it also has limitations such as limited flexibility, inability to be reprogrammed, high programming cost, and limited storage capacity.
