Zusammenfassung:A device includes an array of memory cells, input/output lines coupled to the memory cells, and sense amplifiers coupled to the input/output lines. Each sense amplifier is associated with a respective input/output line. The device also includes trim circuits. Each trim circuit is associated with and coupled to a respective sense amplifier. Each sense amplifier receives a respective reference voltage that allows the sense amplifier to sense a bit value of an addressed memory cell. Each trim circuit is operable for compensating for variations in the reference voltage used by the respective sense amplifier.
