Claim:
1. A current sense amplifier, comprising: a reference current input terminal, a control line input terminal, a sense current input terminal and a first output terminal, the amplifier further comprising: a first NAND gate comprising a second output terminal being coupled to the first output terminal of the amplifier; a first cross coupled inverter comprising a first n-FET and a second cross coupled inverter comprising a second n-FET; a transmission gate comprising first and second transmission terminals and a gate terminal, the gate terminal coupled to the control line terminal; wherein a first source of the first n-FET is coupled to the sense current input terminal and a second source of the second n-FET is coupled to the reference current input terminal, wherein, the first transmission terminal is coupled to a first input terminal of the first cross coupled inverter and the second transmission terminal is coupled to a second input terminal of the second cross coupled inverter; and wherein at least a first input terminal of the first NAND gate is coupled to the control line terminal and at least a second input terminal of the first NAND gate is coupled to at least one of the input terminals of the inverters.
