Question: Design a memory interface for the 8 0 8 6 , which will provide 2 5 6 K bytes of SRAM, organized as 1 2

Design a memory interface for the 8086, which will provide 256K bytes
of SRAM, organized as 128K x 16 bits, starting at address 40000H and
using SRAM chips 32K x 8 bit. The SRAM chipshave three control signals
WR. OE and CS. Use the 74LS138(3- to-8 decoder) for the implementation
of the decoding circuit. The 74LS138 has three control signals G1, G2A, and
G,B.
What is the address space for second chip?
a.40000H -4FFFFH
Db.40000H-50000H
c.40001H -4FFFFH
O d.40000H -4FFFEH
