In a DRAM, a capacitor to store a bit of data is used along with a MOSFET (transfer device) which acts as a switch. The circuit is as shown –

In a DRAM:
  • Periodic refreshing is required.
  • The information is stored in a capacitor.
  • Both read and write operations cannot be performed simultaneously.
