Abstract:
A device having a substrate prepared with a memory cell region having a memory cell is disclosed. The memory cell includes an access transistor and a storage transistor. The access transistor includes first and second source/drain (S/D) regions and the storage transistor includes first and second storage S/D regions. The access and storage transistors are coupled in series and the second S/D regions being a common S/D region. An erase gate is disposed over the common S/D region. A program gate is disposed over the first storage S/D region. Such an arrangement of the memory cell decouples a program channel and an erase channel.
