  • Semiconductor memory device with an improved erroneous write characteristic and erasure characteristic
    Patent number: 5252846
    Abstract: A semiconductor memory device containing a number of memory cells each having a floating gate, an erase gate, and a control gate. In a data erasure mode, electrons are discharged from the floating gate into the erase gate. In the semiconductor memory device, an impurity concentration in at least a region of the floating gate overlapping with the erase gate is lower than that of the erase gate.
    Type: Grant

  • Semiconductor memory device
    Patent number: 4996572
    Abstract: A semiconductor memory device containing a number of memory cells each having a floating gate, an erase gate, and a control gate. In a data erasure mode, electrons are discharged from the floating gate into the erase gate electrode. An insulating film interlaid between the erase gate and the control gate has a three-layered structure consisting of a silicon oxide film, a silicon nitride film, and a silicon oxide film.
