  • Patent number: 11869599
    Abstract: A nonvolatile memory device includes cell strings commonly connected between bitlines and a source line where the cell strings are grouped into memory blocks. During a precharge period, channels of the cell strings of a selected memory block are precharged by applying a gate induced drain leakage (GIDL) on voltage to gates of GIDL transistors included in the cell strings of the selected memory block where the GIDL on voltage has a voltage level to induce GIDL. During the precharge period, precharge of channels of the cell strings of an unselected memory block are prevented by controlling a gate voltage of GIDL transistors included in the cell strings of the unselected memory block to prevent the GIDL. During a program execution period after the precharge period, memory cells of the selected memory block connected to a selected wordline are programmed by applying a program voltage to the selected wordline.

  • Publication number: 20200232462
    Abstract: A motor operated compressor includes an orbiting scroll that defines a compression chamber together with a fixed scroll. The compressor includes a main frame disposed around and supporting the orbiting scroll. The main frame defines a back-pressure chamber together with the orbiting scroll. The compressor includes a groove disposed in one of the orbiting scroll and the main frame. A first sealing member is inserted into the groove. A second sealing member is inserted into the groove to elastically press the first sealing member into close contact with the orbiting scroll or the main frame. A radial distance (a) between an outer wall of the groove and the first sealing member is 6 to 8% (0.06?a/W?0.08) of a difference (W) between an outer radius (OR) and an inner radius (IR) of the first sealing member (W=OR?IR).
