Q. The access time of ROM using bipolar transistors is about ?

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

Explanation by: Admin

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
