WebThe noise margin changes depending on the signal source. Let's say an input stage needs a minimum of 3.0 V to guarantee a (whatever) output. If the signal source makes a nominal 4.0 V output, that is a 1.0 V margin. If it makes a 5.0 V nominal output, that is a 2.0 V margin. WebAug 1, 2024 · 3.1.1.1. Read static noise margin. The read operation is the weakest situation because the cell transistors must be stronger enough to discharge the pre-charged bit-line without flipping its value stored. In a read operation, the memory cell is connected to the bit-lines and the internal nodes are disturbed. how to take care of a pet garter snake
