Question
In an 8085 system, CS = A15’ A14 A13 is used as the chip select of a 4K RAM. What is the memory range of the system? A) 3000-3FFFH B) 7000-7FFFH C) 5000-5FFFH and 6000-6FFFH D) 6000-6FFFH and 7000-7FFFH
Solution
The memory range of the system is B) 7000-7FFFH.
Here's the step-by-step explanation:
- The chip select (CS) is A15' A14 A13. This means that A15 is complemented (i.e., it is always 0) and A14 and A13 can be either 0 or
