Abstract:
1. A sense amplifier of a DRAM comprising, in series between two terminals of application of a power supply voltage: at least one first transistor of a first channel type; and an amplification stage formed of two parallel branches each comprising a second transistor of the first channel type in series with a transistor of a second channel type, the gates of the transistors of a same branch being connected to the junction of the transistors of the other branch, each junction point defining a input/output terminal of the sense amplifier intended to be connected to a bit line, wherein each branch comprises at least one first additional transistor of the first channel type in parallel with at least each second transistor of the first channel type; and wherein each first additional transistor is in series with a second additional transistor of the same type between a first terminal of application of the supply voltage and said junction of the involved branch.
