  • Sensing circuit for EEPROM
    Patent number: 5864502
    Abstract: A sensing circuit for detecting data stored in a memory cell of an EEPROM by current detecting method is disclosed. The sensing circuit includes a constant current source supplying circuit for supplying a constant current. A loading circuit generates a current the same as the constant current generated by the current source supplying circuit when the memory cell sends out a logic low state signal, so that the data accessing speed during reading the data stored in the memory cell is increased.
