Abstract
Memory sense amplifier unit for amplifying a data signal read from a memory via bit lines ( ), having a precharge circuit ( ) comprising PMOS transistors ( ) and serving for rapidly precharging the bit lines ( ) to a supply voltage potential (V ) of the sense amplifier unit ( ); a first amplifier stage ( ) comprising feedback NMOS transistors ( ) and serving for voltage level shifting and for amplifying the data signal present on the bit lines ( ); and having a second amplifier stage ( ) for amplifying further the signal output by the first amplifier stage ( ), in which case the first amplifier stage ( ) can be initialized to the supply voltage potential (V ) and the second amplifier stage ( ) can be initialized to ground potential (V ).
