  1. What will be the starting address of memory chip, given that memory address of last location of an 8K byte memory chip is FFFFH—
    1. DEFFH
    2. E000H
    3. F000H
    4. None of these
Correct Option: B

8 K byte = 1024 × 8 = 8192 memory location (i.e., from 0 – 8191)
Now binary representation of decimal 8191 in 16-bit format is
0001 1111 1111 1111
Given that last location = FFFFH
So, starting address
FFFFH = 1111 1111 1111 1111
–8 K byte = 0001 1111 1111 1111
1110 0000 0000 0000
Therefore, Starting address is E000H.
