    摘要: A method of fabricating a nonvolatile memory device includes preparing a semiconductor substrate having a cell array region and a peripheral circuit region. Cell gate patterns are formed in the cell array region, and peripheral gate patterns are formed in the peripheral circuit region. Each of the cell gate patterns includes a control gate pattern and a capping pattern, and each of the peripheral gate patterns has a smaller thickness than the cell gate pattern. An interlayer dielectric layer is formed on the resultant structure having the cell gate patterns and the peripheral gate patterns. The interlayer dielectric layer is planarized by etching until the top surface of the capping pattern is exposed, so that an interlayer dielectric pattern is formed. The interlayer dielectric pattern covers the peripheral circuit region and fills a space between the cell gate patterns. An ion implantation process is performed using the interlayer dielectric pattern as an ion mask so that impurity ions are selectively implanted into the control gate pattern.

    摘要: A non-volatile memory device includes a first sensing line, a first word line, a depletion channel region, and impurity regions. The first sensing line and the first word line are formed adjacent to each other in parallel on a substrate. The first sensing line and the first word line have a tunnel oxide layer, a first conductive pattern, a dielectric layer pattern and a second conductive pattern sequentially stacked on the substrate. The depletion channel region is formed at an upper portion of the substrate under the first sensing line. The impurity regions are formed at upper portions of the substrate exposed by the first sensing line and the first word line.

    摘要: The present invention is directed to a non-volatile memory device and a method of operating the same. The non-volatile memory device includes a first transistor connected to an nth bitline and a second transistor connected to an (n+1)th bitline. The first transistor and the second transistor are serially coupled between the nth bitline and the (n+1)th bitline. The non-volatile memory device may include a 2-transistor 1-bit unit cell where a drain region and a source region of a memory cell have the same or similar structure. Since a cell array of a non-volatile memory device according to the invention may include a 2-transistor 2-bit unit cell, storage capacity of the non-volatile memory device may be doubled.
