Question 2:
How does a memory array organized as 4 x 16 differ from one organized as 1 x 64?
Answer:
A 4 x 16 memory array stores 16 nibbles, whereas a 1 x 64 memory array stores 64 single-bit values.

Question 5:
How does Static RAM (SRAM) differ from Dynamic RAM (DRAM)?
Answer:
SRAM uses flip-flops for storage and retains data as long as power is supplied, while DRAM uses capacitors that need periodic refreshing to maintain data.

Question 6:
What is a characteristic of ROM compared to RAM?
Answer:
ROM retains data permanently and cannot be written to by users, while RAM is volatile and loses data when power is off.

Question 7:
How is data accessed in a Static RAM memory cell?
Answer:
Data in a Static RAM memory cell is accessed through a flip-flop, which stores binary data as long as power is supplied.

Question 8:
What does the Memory Select signal do in a memory operation?
Answer:
The Memory Select signal activates a specific memory chip to be accessed for read or write operations.

Question 9:
What is the purpose of the Refresh cycle in Dynamic RAM?
Answer:
The Refresh cycle in Dynamic RAM periodically recharges capacitors to prevent data loss.

Question 10:
What determines the memory density?
Answer:
Memory density is determined by the number of bits stored per unit area of the memory.
