Abstract
A sense amplifier (10) senses data by sensing a differential current signal comprised of a current (I.sub.1) flowing in an input terminal (12) and a current (I.sub.2) flowing in a complementary input terminal (22). During the sensing process, the sense amplifier (10) generates a first current flowing in a first FET (17) in accordance with the current (I.sub.1) flowing through the input terminal (12) and a second current flowing in a second FET (27) in accordance with the current (I.sub.2) flowing through the complementary input terminal (22). Two cross coupled inverters (16, 26) compare the first current (I.sub.1) with the second current (I.sub.2) and generate a differential output voltage signal, thereby sensing the data.
