The present invention provides a memory cell and method for preparation. The memory cell includes a pass-gate transistor and a storage region. The transistor includes a gate and a drain. The storage region includes a trench, which is preferably a Shallow Trench Isolation (STI). A non-insulating structure, e.g., formed of polysilicon or metal, is located in the trench as serves as a capacitor node. The trench is partially defined by a doped sidewall that serves as a source for the transistor. The poly structure and the trench sidewall are separated by a dielectric layer. The write operation involves charge transport to the non-insulating structure by direct tunneling through the dielectric layer. The read operation is assisted by Gate Induced Drain Leakage (GIDL) current generated on the surface of the sidewall. The embodiments of the invention reduce size of the device, increase storage time of the charge and increase compatibility between the standard preparing steps.
