Interface 4Kbyte RAM and 2Kbyte ROM with starting address 8000H

[@jayexplains6010]

For 2k byte Value of A11 is zero for starting and ending address because A11 is not connected to 2kbyte memory (see figure).

What happens to A11 if it’s not connected?

Interface 4kB RAM and 2KB ROM with an 8085 microprocessor to
satisfy the total memory requirement of 16kB RAM and 8kB
ROM. Explain the interface diagram and allocate binary
addresses to the memory ICs. Use 74LS373 (octal latch) and
74LS139 (Dual 2 to 4 line decoder)
