How many bits does a $2564$ memory chip store? Can this chip be specified

as $128-$byte memory?

If the $8085$ has fetched the machine code located at the memory location

$205FH,$ specify the content of the program counter.

The memory address of the last location of an $8$K$-$byte block in a memory chip

is FFFFH$.$ Find the starting address.

If the stack segment register contains $3000H$ and the stack pointer register

contains $8434H,$ what is the physical address of the top of the stack?

The memory map of a $4K(4096)-$ byte block in a memory chip begins at the

location $2000$ H$.$ Specify the address of the last location on the chip.
