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. WebJan 28, 2024 · The resilience of an SRAM bit cell to noise margin is measured using the static noise margin (SNM) metric for the read and hold operation. Whereas, for the write operation, the write margin (WM) is calculated.
