    摘要: Provided are a cell structure of an EPROM device and a method for fabricating the same. The cell structure includes a gate stack, which includes a first floating gate, an insulating pattern including a nitride layer, and a control gate that are sequentially stacked on a semiconductor substrate, and includes a window for exposing the top surface or both sidewalls of the first floating gate on both sides of the control gate, so that charges of the first floating gate can be erased by ultraviolet rays. The cell structure further includes a floating gate transistor, which includes a gate insulating layer formed on the semiconductor substrate, a second floating gate that is formed on the gate insulating layer and is connected to the first floating gate in the gate stack, and a source/drain that is formed in the semiconductor substrate so as to be aligned to the second floating gate. In the cell structure, the window is formed on the top surface or both sidewalls of the first floating gate of the gate stack. Thus, ultraviolet rays can penetrate through the window and easily erase charges of the programmed cell.

    摘要: A cell structure of a non-volatile memory device, which uses a nitride layer as a floating gate spacer, includes a gate stack and a floating gate transistor formed over a semiconductor substrate. The gate stack includes a first portion of a floating gate, a control gate formed over the first portion of the floating gate, and a non-nitride spacer adjacent to sidewalls of the first portion of floating gate. The floating gate transistor includes a second portion of the floating gate, which substantially overlaps a source and/or drain formed in the substrate. The application of ultraviolet rays to the non-nitride spacer of a programmed cell can causes the second portion of the floating gate to discharge, thereby easily erasing the programmed cell.

    摘要: A dual port semiconductor memory device, including PMOS scan transistors, is provided. The dual port semiconductor memory device includes two PMOS transistors, two NMOS pull-down transistors, two NMOS pass transistors, and a PMOS scan transistor. The scan transistor being PMOS, noise margins can be improved. In addition, these seven transistors are arranged in two n-wells and 2 p-wells, while n-wells and p-wells are arranged in series and in alternating fashion. Therefore, the length of a memory cell along the minor axis of the memory cell is relatively short. This memory cell layout helps shorten the length of a bit line by arranging a pair of bitlines in parallel with well boundaries, i.e., in the direction of the short axis of the memory cell, and makes it possible to prevent crosstalk between a bitline and a complementary bitline by arranging conductive lines between the bitline and the complementary bitline.
