Explanation:
Detailed explanation-1: -Hence, 18 address buses are required.
Detailed explanation-2: -This implies a direct address space of 64 KB (65, 536 bytes) on most 8-bit processors.
Detailed explanation-3: -The mp would require three address line to place eight different addresses from 000 to 111. The size of this chip can be specified either as 8 byte, 8x8 bit or 64 bit. necessary to form the 8 bit memory word size, resulting 256 bytes of memory.
Detailed explanation-4: -Microprocessors, instrumentation and control In 8-bit systems, with 64K of addressable memory, the memory map is usually composed of 32K of RAM and 32K of ROM or EPROM.
