Show hintHide hint
Recall the definition of a byte.
Question 5.
Design a modular memory system that can be expanded to 8K using 1K x 8 bit chips. Explain how you would manage addressing.
Show hintHide hint
Consider how multiple small modules fit into a larger architecture.
Question 6.
Evaluate the performance implications of using a memory configuration that is narrow (e.g., 4 bits) versus a wider configuration (e.g., 32-bits).
