4) Design and draw these memory units with their control circuits. Explain operations. a) A single EPROM 2716 is used with an 8088 microprocessor so that this microprocessor will see only X bytes of memory between the address range of DF800 –DFFFF or DD800 - DDFFF instead of 1M byte that it expects. Draw this circuit. What are X bytes? Do not use 74138 decoders

4) Design and draw these memory units with their control circuits. Explain operations.
a) A single EPROM 2716 is used with an 8088 microprocessor so that this microprocessor
will see only X bytes of memory between the address range of DF800 –DFFFF or DD800
- DDFFF instead of 1M byte that it expects. Draw this circuit. What are X bytes? Do not
use 74138 decoders.
b) Design and show a 16K x 16-bit memory circuit by using 8K x 8-bit RAMS. Explain its
operation. Do not use decoder 74138 chip.
