    摘要: In a method of reading data in an EEPROM cell, a bit line voltage for reading is applied to the EEPROM cell including a memory transistor and a selection transistor. A first voltage is applied to a sense line of the memory transistor. A second voltage greater than the first voltage is applied to a word line of the selection transistor. A current passing through the EEPROM cell is compared with a predetermined reference current to read the data stored in the EEPROM cell. An on-cell current of the EEPROM cell may be increased in an erased state and the data in the cell may be readily discriminated.

    摘要: a nonvolatile memory device Includes an active region defined in a semiconductor substrate and a control gate electrode crossing over the active region. A gate insulating layer is interposed between the control gate electrode and the active reigon. A floating gate is formed in the active region to penetrate the control gate electrode and extend to a predetermined depth into the semiconductor substrate. A tunnel insulating layer is successively interposed between the control gate electrode and the floating gate, and between the semiconductor substrate and the floating gate. The floating gate may be formed after a trench is formed by sequentially etching a control gate conductive layer and the semiconductor substrate, and a tunnel insulating layer is formed on the trench and sidewalls of the control gate conductive layer. The floating gate is formed in the trench to extend into a predetermined depth into the semiconductor substrate.

    摘要: A non-volatile memory device includes a floating gate formed on a substrate with a gate insulation layer interposed therebetween, a tunnel insulation layer formed on the floating gate, a select gate electrode inducing charge introduction through the gate insulation layer, and a control gate electrode inducing charge tunneling occurring through the tunnel insulation layer. The select gate electrode is insulated from the control gate electrode. According to the non-volatile memory device, a select gate electrode and a control gate electrode are formed on a floating gate, and thus a voltage is applied to the respective gate electrodes to write and erase data.

    摘要: In a split gate type nonvolatile memory device, a supplementary layer pattern is disposed on a source region of a semiconductor substrate. Since the source region is vertically extended by virtue of the presence of the supplementary layer pattern, it is therefore possible to increase an area of a region where a floating gate overlaps the source region and the supplementary layer pattern. Accordingly, the capacitance of a capacitor formed between the source and the floating gate increases so that it is possible for the nonvolatile memory device to perform program/erase operations at a low voltage level.
