ABSTRACT:
An EEPROM device having dual EEPROM transistor blocks for storing a charge and a current mirror for determining the difference in charge between the EEPROM transistor blocks. During a write operation, one EEPROM transistor block is charged while the other block is discharged. During a read operation, the current mirror attempts to supply equal current to each of the EEPROM transistor blocks. However, because each block has a different charge, more current will be forced through one leg of the current mirror. This results in a voltage difference across the legs of the current mirror which can be read by a voltage sensor.
