Solution
The question is asking which statement is not true during a memory read operation. Here are the statements broken down:
a. To communicate with memory, the MPU (Micro Processing Unit) places a 16 bit address on the address lines. This is true. The MPU communicates with the memory by placing an address on the address lines.
b. It is the MPU which generates these control signals especially when it performs memory read or write operations. This is also true. The MPU generates control signals for memory read or write operations.
c. The MPU sends a pulse called memory read as the control signal. This is true as well. The MPU sends a control signal, often referred to as a memory read signal, when it wants to read data from memory.
d. None of the above. This option suggests that all of the above statements are true.
e. The addresses are the decoded by an external logic circuit and the memory is identified. This statement is not entirely clear, but it seems to suggest that the addresses are decoded by an external logic circuit, which then identifies the memory. This is generally true, but the phrasing is a bit awkward.
Based on these explanations, it seems that all the statements are true, so the correct answer would be (d) None of the above. However, without more context or a clearer phrasing of option (e), it's difficult to say for certain.
