Explanation:
DRAM:
DRAM stands for Dynamic Random Access Memory. It is a type of volatile memory used in computers and other electronic devices for storing and accessing data. DRAM is based on a storage cell called a capacitor, which can store a small amount of electrical charge.
Information Storage in a Capacitor:
In a DRAM, information is stored in a capacitor. Each bit of data is stored as an electrical charge in a capacitor within the memory cell. The presence or absence of charge represents the binary values 1 and 0, respectively.
Periodic Refreshing:
Unlike other types of memory, such as SRAM (Static Random Access Memory), DRAM requires periodic refreshing of its memory cells. This is because the electrical charge stored in the capacitors tends to leak away over time due to the inherent properties of the capacitor. If the charge is not refreshed, the data stored in the memory cells will be lost.
Read and Write Operations:
Both read and write operations can be performed in a DRAM. To read data from a specific memory cell, the charge stored in the capacitor is sensed and amplified, and then the data is outputted. To write data into a specific memory cell, the charge in the capacitor is changed to represent the desired data value.
Simultaneous Read and Write:
Simultaneous read and write operations are not possible in a DRAM. When a read operation is performed, the charge in the capacitor is read and the data is outputted. During a write operation, the charge in the capacitor is changed to store the desired data value. These operations cannot be performed simultaneously on the same memory cell.
Conclusion:
In conclusion, in a DRAM, information is stored in a capacitor, and periodic refreshing is required. Both read and write operations can be performed, but not simultaneously on the same memory cell.

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.
