Web2 Static Noise Margins Conventional static noise margins (SNMs) characterize a memory cell’s noise im-munity under the DC condition, i.e. with the injection of static noises. SNMs can be computed in several different but equivalent ways [1]. Among these, for instance, static noise margins in hold and read can be determined as shown in Fig. 1 ... 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.

Web4.1 Read Static-Noise-Margin During read accesses, the Read-SNM decreases [8]. This is due to the reason that Read-SNM is calculated when the word line is set high and both bit line are still precharged high. At the onset of a read access, the access transistor (WL) is set to “1” and the bit-lines are already precharged to “1”.The
