Hey,
I am interested in knowing about the insides of a RAM card. I want to know what type of capacitors they use in RAM cards, how are they made and what is the maximum capacitance of these capacitors?... Also what type of transistors they use in the memory cells.

How is the data read? I understand that a sense amplifier is used, but what does it do and how does it work? and how is it able to detect multiple cells at the same time or are the cells read serially? one after the other.

If there is some source that explains these things in detail.. It would be very helpful..

When you talk about the RAM card are you talking about the memory you put in the dimm slots?

yeah... exactly... Not flash cards, RAM cards, the ones that you insert into the DIMM slots of your motherboard, the volatile ones..
 

FAQ: Inside a RAM Card: Capacitors, Transistors, & Sense Amplifier

What is the purpose of a RAM card?

A RAM card, or Random Access Memory card, is used to store data temporarily in a computer. It allows for quick access and retrieval of data, making it essential for the functioning of a computer.

What are capacitors and how are they used in a RAM card?

Capacitors are electronic components that store energy in an electric field. In a RAM card, capacitors are used to store bits of data in the form of electrical charges. They hold this charge until it is read or changed by the computer.

What is the role of transistors in a RAM card?

Transistors are used in a RAM card as switches to control the flow of electricity to and from the capacitors. They allow for the reading and writing of data in the RAM card by opening and closing circuits.

What is a sense amplifier and how does it work in a RAM card?

A sense amplifier is a circuit that amplifies the small signals from the capacitors in a RAM card to make them readable by the computer. It compares the voltage levels of the capacitors and determines whether they represent a 1 or 0, which corresponds to the stored data.

How does data get stored and retrieved in a RAM card?

Data is stored in a RAM card by first writing it to the capacitors using transistors. When the computer needs to retrieve the data, the sense amplifier reads the voltage levels of the capacitors and sends the data to the computer's processor. The data is then cleared from the capacitors to make room for new data to be stored.
