Abstract:
1. A sense amplifier circuit comprising: a pair of cross-coupled inverters comprising a first inverter and a second inverter, the first inverter having a first pull-up transistor with a first pull-up terminal and a second pull-up terminal, the second pull-up terminal of the first pull-up transistor connected to a first sense amp node, the second inverter having a second pull-up transistor with a first pull-up terminal and a second pull-up terminal, the second pull-up terminal of the second pull-up transistor connected to a second sense amp node, the output of the first inverter coupled to the input of the second inverter at the first sense amp node, the output of the second inverter coupled to the input of the first inverter at the second sense amp node; and a data line charging circuit having a first node connected to a data line and the first pull-up terminal of the first pull-up transistor, the data line charging circuit also having a second node connected to a complementary data line and the first pull-up terminal of the second pull-up transistor.
