How many address lines are necessary to access 64K x 8 memory system using 8K x 8 memory chips?

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.

∙ 12y agoIt does not matter what size the memory chips are. If the memory system is 64K x 8, then you need 16 address lines to access it.
Perhaps you meant to ask how many address lines per chip. If so, there would be 8 chips and you would use 3 address lines to select which chip, with the remaining 13 address lines being common to all 8 chips.
However, note that this will fill up the address space of an 8085, and leave no room for any boot ROM, so it does not look like a viable configuration, unless you intend to do some kind of bank switching. Or, maybe, one of the 8 chips is a ROM?

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!
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 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.
Which memory is optional to start a computer system?
Random access memory (ram)
What is sd ram memory?
Synchronous dynamic random access memory (in other words fast access memory that the computer uses for the operating system/kernal, and running programs)
What are the 2 types of memory called in a computer system?
RAM (Random Access Memory) and ROM (Read Only Memory).
What is the name of the file the operating system uses when it moves data from random access memory to virtual memory?
A swap file is the file that an operating system uses when it is moving data. A computer creates this file when it is moving data from random access memory to virtual memory.
What function of file system in operating system?
File system in OS provide the way to create and access the files. How the memory is allocated to files and how the addresses are saved regarding to each file. All this is about the address translation and calculation for files.
What is the key task of a memory system?
The key task of a memory system is to memorize data in such a way as to have it readily available to the user. This is why computers have RAM (Random Access Memory).
Why does memory access take more machine cycle than register access?
Because of different in speeds of cpu the system bus and the memory circut
