Memory expansion based on the word size is most efficient method of expanding memory in intel 8085Question 15Select one:TrueFalse

Analysis of the Statement

The statement claims that memory expansion based on word size is the most efficient method of expanding memory in the Intel 8085. To evaluate this, we need to consider how the Intel 8085 architecture handles memory and data.

1. Intel 8085 Architecture: The Intel 8085 microprocessor has a 16-bit address bus, which enables it to access up to 64 KB of memory. Its word size is 8 bits, meaning it processes data in 8-bit chunks.

2. Memory Expansion Methods: Common methods for memory expansion include:

   • Bank Switching: This involves adding extra memory chips and managing them through software.
   • Using larger data buses: Expanding memory by using methods that allow larger data transfers.

3. Efficiency Consideration: The efficiency of memory expansion methods can depend on various factors such as speed, complexity of implementation, and cost. Simply expanding based on the word size (8 bits) may not maximize the potential of the available address space (64 KB).

Conclusion

Based on the structure of the Intel 8085 and the types of memory expansions available, we find that the statement is:

Final Answer: False. Memory expansion based solely on word size may not be the most efficient method for the Intel 8085 architecture.
