Question

How many types of semiconductor memory a computer using?

Answer 1

Once upon a time, in huge city there was a man who was returning to his home from a party.While he was going on his way he saw a old beggar . The beggar asked for some food or money so that he can survive.
The man was drunked so he took a lot of time to recognise that the person who is begging is a beggar. As he was drunked he gave him Rs.10,000. The beggar became very happy ,as the man was also carrying some food from the party he gave all that food.

Later on in his life the old poor beggar became a very rich businessman .And he lives rest of his life happily

Answer 2

This type is used for the main memoryin most computers, since data is stored on the hard disk while thecomputer is off. Major types are: DRAM (Dynamic random-accessmemory) which uses memory cells consisting of one capacitor and one transistor to store each bit.

With the rapid growth in the requirement for semiconductor memories there have been a number of technologies and types of memorythat have emerged. Names such as ROM, RAM, EPROM, EEPROM, Flash memory, DRAM, SRAM, SDRAM, and the very new MRAM can now be seen in the electronics literature.
