Methods and an apparatuses for generating a word-line voltage are disclosed. A word-line voltage generator includes a first current source, an adjustable current source, adjustable current sink, and a voltage converter, all operably coupled to a current sum node. The first current source generates a first current having a temperature coefficient substantially equal to a temperature coefficient of at least one-bit cell. The adjustable current source generates a second current that is substantially independent of a temperature change. The adjustable current sink sinks a third current that is substantially independent of a temperature change. The voltage converter is configured for generating a word-line signal having a word-line voltage proportional to a reference current, wherein the reference current comprises the first current, plus the second current, and minus the third current.
