Abstract:
A sense amplifier for ascertaining a memory content of a memory device, comprising:an input receiving an input signal characterizing a content of a memory device in a first memory state or profile and in a second memory state or profile, and an output carrying an output signal representing the content of the memory device; a comparator device for comparing a current or a voltage of the input signal with a threshold value and determining therefrom a memory content of the memory device; wherein the threshold value is defined as a first threshold value to be exceeded or undershot by the input signal in order for the output signal representing the content of the memory device to change from the first state or profile to the second state or profile, and as a second threshold value, higher or lower than the first threshold value, to be exceeded or undershot by the input signal in order for the output signal to change from the second state or profile to the first state or profile.
