Abstract
The present disclosure relates to a method and apparatus for determining a signal margin (SM) of a memory cell, a storage medium and an electronic device, and relates to the technical field of integrated circuits. The method for determining an SM of a memory cell includes: when the memory cell performs write and read operations, determining a sense signal threshold of the memory cell under an influence of a noise; and determining, based on the sense signal threshold, an actual SM of the memory cell during data reading.
