Abstract
A configurable mirror sense amplifier system for flash memory having the following features. A power source generates a reference voltage. A plurality of transistors is biased at the reference voltage. The plurality of transistors is each coupled to a second transistor. Each of the plurality of transistors is also configured to provide a current for comparison with the flash memory. The reference voltage is internal, stable and independent from variations of a power supply or temperature. The plurality of transistors is in parallel with one another. A mirror transistor is coupled to the plurality of transistors. The plurality of transistors is configured so that at least one of at least one transistor is activated with a signal in order to provide the current for comparison to the flash memory. Also, the reference voltage may be modified in order to modify the current for comparison to the flash memory.
