The present invention provides a method of memory cell selection and operation to obtain wide program bandwidth and EEPROM erase capability. Two storage sites within a memory cell can be simultaneously selected during read, program and erase. By proper biasing, each of the sites can be independently read and programmed. Also, during program, the source of energy to produce the current flow can be dynamically obtained from the stored charge on the selected bit line. If the bit line capacitance is not adequate to provide a charge that is necessary, additional bit line capacitance is borrowed from unselected bit lines, or a source follower select transistor may be used.
