    摘要: In a method for forming a semiconductor device and a semiconductor device formed in accordance with the method, a thin dielectric layer is provided between a lower conductive layer and an upper conductive layer. In one embodiment, the thin dielectric layer comprises an inter-gate dielectric layer, the lower conductive layer comprises a floating gate and the upper dielectric layer comprises a control gate of a transistor, for example, a non-volatile memory cell transistor. The thin dielectric layer is formed using a heat treating process that results in reduction of surface roughness of the underlying floating gate, and results in a thin silicon oxy-nitride layer being formed on the floating gate. In this manner, the thin dielectric layer provides for increased capacitive coupling between the lower floating gate and the upper control gate. This also leads to a lowered programming voltage, erasing voltage and read voltage for the transistor, while maintaining the threshold voltage in a desired range. In addition, the size of the transistor and resulting storage cell can be minimized and the need for a high-voltage region in the circuit is mitigated, since, assuming a lowered programming voltage, pumping circuitry is not required.

    摘要: An EEPROM includes a tunneling opening having an inclined or a stepped sidewall. A tunnel insulation layer is formed within the tunneling opening. Using a flowed photoresist pattern as an etching mask, the gate insulator is etched to form a tunneling opening having an inclined sidewall. Thus, the tunnel insulation layer can be formed in a smaller area than an area defined by a photolithography. As a result, a width of an active region and a width of a wordline are decreased to reduce a unit cell size.

    摘要: A method and an apparatus for pre-scheduling in a closed-loop multiple user multiple input multiple output (MU-MIMO) antenna system. A base station receives channel information representing a downlink channel condition of each mobile station from mobile stations in a cell, and determines a candidate user group for each of frequency bands included in an entire frequency band, based on the channel information, the candidate user group including mobile stations to which resources can be simultaneously allocated. The base station also instructs a mobile station included in each candidate user group to transmit a sounding signal through a corresponding frequency band. If the sounding signal is received through the corresponding frequency band, the base station performs a scheduling with regard to the mobile station included in each candidate user group.

    摘要: A partial iterative detection and decoding apparatus in a Multiple Input Multiple Output (MIMO) system includes a detector for detecting signals received through at least one receive antenna to generate a first soft decision value, a decoder for decoding the first soft decision value to generate a second soft decision value, and a reliability determiner for determining a signal to be iteratively detected and decoded by using the second soft decision value. Accordingly, the complexity of the receiver is reduced and the number of iterations limited due to the complexity is increased, thereby improving the performance of the receiver.
