Abstract

See full text

A sense amplifier is provided. A first terminal of a first invertor is connected to a power node and a second terminal of the first invertor is connected to a cell current source. A first terminal of a second invertor is connected to the power node and a second terminal of the second invertor is connected to a reference current source. The first invertor is cross coupled with the second invertor at a first node and a second node. A pre-charge circuit is connected to the first node and the second node. A first pull up transistor and a second pull up transistor are connected between a supply voltage node and the power node. A signal level detector circuit is connected to the second pull up transistor. The signal level detector circuit switches on the second pull up transistor when a remaining voltage on one of the first node and the second node is below a reference voltage.
