Question

On the basis of concepts of interfacing of memories show that how the RAM of 32 KB can
be interfaced with 8085 MP and its starting Address is 4000H . Draw a complete diagram of
interfacing and find the range of memory used by RAM .

Answer 1

Explanation:

The programs and data that are executed by the microprocessor have to be stored in ROM/EPROM and RAM, which are basically semiconductor memory chips. The programs and data that are stored in ROM/EPROM are not erased even when power supply to the chip is removed. Hence, they are called non-volatile memory. They can be used to store permanent programs.

In a RAM, stored programs and data are erased when the power supply to the chip is removed. Hence, RAM is called volatile memory. RAM can be used to store programs and data that include, programs written during software development for a microprocessor based system, program written when one is learning assembly language programming and data enter while testing these programs.
