A twin non-volatile memory cell on unit device and method of operating the same are disclosed. The device is formed in the n-well and compatible with CMOS processes comprising a selecting gate, two ONO spacers, a p+ source/drain, and n extended source/drain. To program the cells, two strategies can be taken. One is by a band to band hot electron injection can be carried out. The other is by channel hot hole induced hot electron injection. To read the right cell of the twin nonvolatile cells, a reverse read is taken so as to shield the left cell. In the reading process, the biased on the selecting gate and the source electrode have to make sure the tapered main channel beneath selecting gate has its narrower end through the depletion boundary to connect the second channel beneath the extended source. To erase the datum in the selected cell, two approaching can be carried out. One is by FN erase, the other is by band to band induced hot hole injection.

This invention provides a memory array and it support signals and a method for byte access for programming, erasing and reading memory cells. The advantage of this array and method is the ability to access bytes for program, erase, and read operations. This array and method uses an added isolation transistor to isolate the high voltage from the unselected byte. In addition, it utilizes a separate source line for each byte in a row. This source line is also shared by a byte in a different row. The array has very little peripheral circuit overhead requirement and it avoids programming disturbances of unselected memory cells.
