(A) 1 sec
(B) 1 mili sec
(C) 1 micro sec
(D) 1 n sec

💬 Discuss

✅ Correct Answer: (C) 1 micro sec

Explanation: Access time is the time taken to read a stored word after applying address bits. Bipolar memories have a faster access time than MOS memories. Typical MOS EPROM has an access time of 450 n seC. Bipolar PROM has 80 n sec. So, option (c) is most appropriate
