  • Publication number: 20240145017
    Abstract: Disclosed is a memory device which a memory cell array including a plurality of memory blocks, a voltage generator configured to generate an erase voltage and row line voltages to be provided to a target block from among the plurality of memory blocks, in which an erase operation is to be performed, and control logic configured to control the memory cell array and the voltage generator. The voltage generator is configured to provide the erase voltage to at least one of a bit line and a common source line connected with the target block and to provide the row line voltages to row lines connected with the target block, and the control logic is configured to change a slope of the erase voltage and a floating time of at least one row line among the row lines depending on a program/erase cycle.

  • Publication number: 20230354862
    Abstract: The present invention relates to an anti-diabetic composition comprising a fermented product obtained by low-temperature aging a mixture of beets, carrots and apples. More specifically, an aged product, obtained by low-temperature aging of a mixture obtained by extracting and blending juices of beets, carrots and apples in a weight ratio of 1.5-3.5:1.5-2.5:4-7, has excellent blood sugar-reducing effects, such as concentration-dependent suppression of ?-glucosidase and ?-amylase activity, blood sugar reduction, reduction of fructosamime, insulin, HOMA-IR and HOMA-? content in the blood, and reduction of the area of ? cells in Langerhans islands in pancreatic tissue, and thus can be useful as an anti-diabetic composition.

  • Publication number: 20230152982
    Abstract: A memory device includes a memory block including a first adjacent word line, a selected word line, and a second adjacent word line provided in a direction perpendicular to a substrate and an address decoding circuit. In a first setup period in which the selected word line is set up, the address decoding circuit is configured to apply a first pre-setup voltage to the first adjacent word line, apply a first setup voltage that is higher than the first pre-setup voltage to the first adjacent word line, apply a second pre-setup voltage to the second adjacent word line, and apply a second setup voltage that is higher than the second pre-setup voltage to the second adjacent word line. The first pre-setup voltage is higher than the second pre-setup voltage.
