14 lines can address 16,384 locations. The 8085, however, has 16 lines, and can address 65,536 locations.

The system design, of course, may limit that to 14, so 16,384 is the answer in that case.

What is the difference between memory address and memory addressability?

A memory address is a specific location in a computer's memory where data is stored. Memory addressability refers to the maximum amount of memory that a computer system can access and use. In other words, memory addressability is the range of memory addresses that a computer can access, while a memory address is a specific location within that range.


How many address lines are necessary to access 2k x 8 memory system using 256 x 8 memory chips?

Why do you want to waste 99.22% of the memory in these chips you supposedly will be spending good money on? Buy smaller sized memory chips more suitable for your purposes and design with them!


What is a correct way to write the value 0xaa55 to physical memory address 0x67a9?

To write the value 0xaa55 to the physical memory address 0x67a9, you would typically use a direct memory access method in a programming language that supports low-level memory manipulation, such as C or assembly. For example, in C, you might use a pointer: *(volatile unsigned short *)0x67a9 = 0xaa55;. This ensures that the value is written directly to the specified address in memory. Remember to ensure that you have the necessary permissions and that the memory address is valid for your system.


Can microprocessor 8085 take memory A000?

Yes, the 8085 microprocessor can access memory location A000, as it has a 16-bit address bus that allows it to address up to 64KB of memory, ranging from 0000 to FFFF in hexadecimal. The address A000 falls within this range, meaning the 8085 can read from or write to this memory location. However, the actual access depends on the system's memory configuration and whether that specific address is mapped to valid RAM or ROM.


What is the purpose of the direct mapped cache tag in a computer system's memory management?

The purpose of the direct mapped cache tag in a computer system's memory management is to quickly determine if a requested memory address is stored in the cache memory. This helps improve the system's performance by reducing the time it takes to access data from the main memory.


What does the size of the address bus affect?

The size of the address bus affects the maximum amount of memory a computer can directly access. Specifically, it determines the number of unique memory addresses that can be generated, which is calculated as 2 raised to the power of the address bus size (in bits). For example, a 32-bit address bus can address up to 4 GB of memory, while a 64-bit address bus can theoretically access 16 exabytes. Thus, a larger address bus allows for greater memory capacity and can enhance overall system performance.


How long can a memory be stored in a random access memory?

Indefinitely, as long as power is not removed from the system. Once power is removed, all address locations in RAM revert to their default state.


What is the formula to calculate the average memory access time in a computer system?

The formula to calculate the average memory access time in a computer system is: Average Memory Access Time Hit Time Miss Rate x Miss Penalty


How does memory access impact the overall performance of a computer system?

Memory access impacts the overall performance of a computer system by affecting how quickly data can be retrieved and processed. Faster memory access speeds up the execution of programs and tasks, leading to improved system performance. Slow memory access can cause delays and bottlenecks, slowing down the computer's operations.


What should be the minimum size of address bus?

The minimum size of an address bus depends on the amount of memory the system needs to access. To calculate the minimum size, you can use the formula (2^n), where (n) is the number of bits in the address bus and determines the number of unique addresses it can generate. For example, a 32-bit address bus can address (2^{32}) locations, or 4 GB of memory. Therefore, the minimum size of the address bus must be large enough to accommodate the maximum memory requirement of the system.


What are Base and Limit registers?

Base and Limit registers are hardware registers used in computer systems to define the memory range that a program can access. The Base register stores the starting memory address of a program, while the Limit register stores the size of the memory range that the program can access relative to the base address. This mechanism helps prevent programs from accessing memory outside of their allocated range, enhancing system security and stability.
