Abstract:
A method of reading a flash memory Electrically-Erasable Programmable Read-Only Memory (EEPROM) memory cell in a flash memory device that includes a multitude of field effect transistor memory cells each having a source electrically connected to a common source terminal, a drain electrically connected to a bitline, a floating gate, a control gate electrically connected to a wordline, a p-well electrically connected to a common p-well terminal, and a substrate, the method comprising:(a) applying a positive voltage to the bitline to which the cell being read is attached;(b) applying a positive voltage to the wordline to which the cell being read is attached;(c) applying zero volts to the common source terminal; and(d) applying a positive voltage to the common p-well terminal.
