  • Patent number: 9496016
    Abstract: A memory cell includes a metal oxide semiconductor (MOS) capacitor including a gate coupled to a storage node and an electrode coupled to a synchronization control line. The MOS capacitor adds a coupling voltage to the gate based on a change in voltage on the synchronization control line. The coupling voltage may maintain the storage node within a predetermined range.
    Type: Grant

  • Patent number: 7539074
    Abstract: A semiconductor device includes a fuse part including an antifuse that is connected between a first common node to which a high voltage that is higher than an internal boost voltage is applied and a first node. The fuse part is enabled in response to a program mode selection signal and an address signal so as to fuse the antifuse in response to the high voltage applied to the first common node and to set a voltage level of a second node. A latch circuit is configured to latch an output signal responsive to the voltage level of the second node when the fuse part is in a fused state. A protection circuit is configured to lower a voltage level at the first node when the fuse part is not enabled and the high voltage is applied to the first common node.

  • Patent number: 6579757
    Abstract: A method of fabricating a semiconductor device, includes the steps of forming gates in a cell region and in a peripheral region of a substrate, forming a polysilicon layer over an entire surface of the resultant structure, partially removing portions of the polysilicon layer in the cell region to maintain the polysilicon layer of a predetermined thickness in the cell region, removing the predetermined thickness of the polysilicon layer both in the cell and peripheral regions, so that the resultant structure includes exposed gates in the cell region but no exposed gates in the peripheral region, and forming an insulating layer over the resultant structure.
