How do transistors work as memory cells and what is the shrinking bit?

[nabil__]

Transistors are tiny crystal of silicon. Transistor switch and it's support component are memory cell.
A single memory chip can hold up to 4 transistor ? What is the shrinking bit ?
Can you please explain?

hi there
welcome to PF
all your questions could have been answered on google
here's something to get you started.....

A single memory chip can hold up to 4 transistor ?

a few more than that ....

eg.
a 64Mb Dynamic RAM chip has over 67 million transistors on it
a 1Gb Dynamic RAM chip has over 1 billion transistors on it

What is the shrinking bit ?

not 100% sure of what you are referring to ... maybe this ...

the number of atoms of material needed to be able to store 1 bit of dataDave

@nabil__

you just quoted me with no words from you ... did you want to ask or say something else ?

Yes. Is the following diagram ( attached ) performs operation with the previous diagram attached ?
How and why ?

This is equivalent to memory cell except the complexity of circuits are hidden.

How to calculate that how many memory cell a memory chip can hold ?

DRAM does not use a 4-transistor cell, they store the information in a capacitor.
