Abstract
A memory circuit includes a memory cell, a data line coupled to the memory cell, a sense amplifier having an input terminal, a precharge circuit coupled to the input terminal of the sense amplifier, a first transistor of a first type, and a second transistor of the first type. The first transistor is coupled between the input terminal of the sense amplifier and the data line, and the second transistor is coupled between to the input terminal of the sense amplifier and the data line. The first transistor has a first threshold voltage, and the second transistor has a second threshold voltage lower than the first threshold voltage.
