Abstract
Embodiments provide a method for sense margin detection for a sense amplifier and an electronic device. The method includes: writing first data and second data respectively to a first memory cell and a second memory cell connected to a first bit line, the first memory cell and the second memory cell being respectively connected to a first word line and a second word line adjacent to each other, and the first bit line being connected to a first sense amplifier; performing a reverse write operation on the first memory cell and the second memory cell; performing write operations on memory cells connected to the second bit line; and reading the second memory cell, and determining the preset row precharge time to be a margin value of row precharge time of the first sense amplifier when the first data is not correctly read.
