- Question
For the given circuit, which of the following is correct?
Options- A. The number 5 is being written to the memory at address location 203.
- B. The chip has not been enabled, since the EN terminal is 0; therefore, nothing will be written to the chip and the output is tri-stated.
- C. Decimal 10 is being written into memory location 211.
- D. The read/write line is LOW; therefore, decimal 5 is being stored at memory location 211.
- Correct Answer
- Decimal 10 is being written into memory location 211.
