    摘要: An EEPROM (100) comprises a source region (122), a drain region (120); and a polysilicon layer (110). The polysilicon layer (110) comprises a floating gate comprising at least one polysilicon finger (112A-112E) operatively coupling the source region (122) and drain region (120) and a control gate comprising at least one of the polysilicon fingers (112A-112E) capacitively coupled to the floating gate. The EEPROM (100) has a substantially reduce area compared to prior art EEPROM since an n-well region is eliminated.

    摘要: Disclosed are devices and associated methods for manufacturing an EEPROM memory cell (10) for use on a negatively biased substrate (12). The invention may be practiced using standard semiconductor processing techniques. Devices and methods are disclosed for a floating gate transistor for use as an EEPROM cell (10) including a DNwell (14) formed on a P-type substrate (12) for isolating the EEPROM cell (10) from the underlying P-type substrate (12).
