Apparatus and method for a configurable mirror fast sense amplifier

A configurable mirror sense amplifier system for flash memory comprising:

• a power source generating a reference voltage;
• an array wherein the array comprises a plurality of transistors each of which is coupled to a means for selecting, the group of transistors biased at the reference voltage and configured to provide a current for comparison with the flash memory;
• and
• a cascode structure coupled to the plurality of transistors and configured to bias the plurality of transistors in order to reduce Early effect.

A method of configuring a mirror sense amplifier system for flash memory comprising:

• determining a current sunk by one or more reference transistors;
• selecting a configuration of at least one reference transistor based on the current sunk by the at least one reference transistor;
• and
• comparing the sum of the current with a cell current of a memory cell in the flash memory.

A method of configuring a mirror sense amplifier system for flash memory comprising:

• selecting at least one transistor such that a sum of the current flowing through the at least one transistor approximates a suitable current reference;
• adjusting the gate voltage on at least one of the at least one transistor such that the current flowing through the one or more groups of transistors approximates a suitable current reference;
• and
• comparing the sum of the current with a cell current of a memory cell in the flash memory.
