    摘要: A NVM device encompasses a MOS select transistor including a select gate electrically connected to a word line, a first source doping region electrically connected to a source line, and a first drain doping region. A MOS floating gate transistor is serially electrically connected to the MOS select transistor. The MOS floating gate transistor comprises a floating gate, a second source doping region electrically connected to the first drain doping region of the MOS select transistor, and a second drain doping region electrically connected to a bit line. The second source doping region and the second drain doping region define a floating gate channel. When the MOS floating gate transistor is programmed via a hot electron injection (HEI) mode, the floating gate is a P+ doped floating gate; when the MOS floating gate transistor is programmed via a hot hole injection (HHI) mode, the floating gate is an N+ doped floating gate.

    摘要: An electrically erasable programmable logic device (EEPLD) contains a P-type substrate. A first N-type doped region is disposed in the P-type substrate. A first gate, which is used to store data, overlies the P-type substrate and is adjacent to the first N-type doped region. A second N-type doped region is laterally disposed in the P-type substrate. The second N-type doped region is also adjacent to the first gate. A second gate, which acts as a select gate or select gate of the EEPLD, overlies the P-type substrate and is adjacent to the second N-type doped region. A third N-type doped region is disposed in the P-type substrate. The third N-type doped region is adjacent to the second gate. By Applying a sufficient voltage on the first N-type doped region (VBL), and changing a select gate voltage (VSG) or the third N-type doped region voltage (VSL) applied on the second gate of the EEPLD, the operation of the EEPLD can be selectively implemented either under a channel hot hole (CHH) program mode or a channel hot electron (CHE) erase mode.
