Question

The memory address of the last location of a 1K byte memory chip is given as FBFF H. Specify the memory map?

Answer 1

1 K byte = 1024 memory location. (i.e., from 0 – 1023)

Now, binary representation of decimal 1023 in 16-bit format is 0000 0011 1111 1111

Given last location = FBFFH

So, starting address

FBFFH = 1111 1011 1111 1111

–1 K byte = 0000 0011 1111 1111

1111 1000 0000 0000

Therefore, starting address is F800H.
