Compensation circuit for generating read/program/erase voltage

A compensation circuit comprising:

• a reference current generating circuit configured to output a reference current of a fixed magnitude;
• a compensation current generating circuit configured to output a compensation current having a magnitude selected proportionally to a magnitude of the reference current based on a code;
• a current mirror circuit configured to output to the reference current generating circuit a first current based on the reference current, to output a second current based on the compensation current, and to output a compensation voltage based on the first current and the second current;
• and
• an output transistor configured to output a sensing voltage based on the compensation voltage,
• wherein a magnitude of the sensing voltage is associated with a magnitude of the second current such that the magnitude of the sensing voltage is a reference magnitude when the code is a reference value, and the magnitude of the second current is increased by the reference magnitude when a value of the code is increased by the reference value.

A voltage generating circuit comprising:
