Abstract
A method for operating a single-poly, single-transistor (1-T) non-volatile memory (NVM) cell. The NVM cell includes a gate on a P substrate, a gate dielectric layer, an N drain region and an N source region. N channel is defined between the N drain region and N source region. The NVM cell is programmed by breaking down the gate dielectric layer. To read the NVM cell, a positive voltage is provided to N drain region, a positive voltage is provided to the gate, and grounding the N source region and the P substrate.
