Abstract
A method for determining a sense boundary of a sense amplifier includes: writing first data into a memory array; reading the first data in a first memory cell of the memory array, and reversely writing second data into the first memory cell; reading, after a preset row precharge time, the first data in a second memory cell on a bit line where the first memory cell is located; and reversely writing the second data into the second memory cell when the first data is read in the second memory cell.
