Patent ID: 7974134

Claim:
Circuitry for use in a non-volatile storage system, comprising: a current mirror circuit comprising a reference current path and a mirror current path, the reference current path receives a reference current which is mirrored in the minor current path; a first transistor in the minor current path, the first transistor is matched to a voltage-setting transistor in at least one sense amplifier, and the mirror current path provides a voltage to the voltage-setting transistor, in response to which the voltage-setting transistor sets an initial voltage at a sense node in the at least one sense amplifier at a start of a sensing period; a resistor connected in series with the current minor circuit; and a second transistor connected in series with the current minor circuit, the second transistor is matched to a voltage-sensing transistor in the at least one sense amplifier, the voltage-sensing transistor senses a final voltage at the sense node at the end of the sensing period.
