  • Publication number: 20130058169
    Abstract: In a non-volatile memory system, a plurality of main memory cells for storing data is arranged in a data cell array and a plurality of reference memory cells is arranged in a reference cell array. The reference cell array includes first reference word lines connected to first reference memory cells and extending, second reference word lines connected to second reference memory cells and extending alternately with the first reference word lines, reference bit lines to which the first and the second reference memory cells are alternately connected in a line and a combined cell having a pair of the first and second reference memory cells and generating a reference signal for processing the data. The first and the second reference memory cells have different cell characteristics. The stability of the reference signal is improved irrespective of the differentiation of the first and the second reference memory cells.

  • Publication number: 20130016558
    Abstract: In a method of storing data in a nonvolatile memory device, a program operation is performed on target memory cells among a plurality of memory cells based on a program voltage. A verification operation is performed on the target memory cells based on a verification voltage to determine whether all of the target memory cells are completely programmed. The verification voltage is changed depending on the program operation.

  • Publication number: 20120219985
    Abstract: The present invention relates to a method for the toxicity assessment of nano-materials, and more specifically, it is relates to an objective, reproducible and accurate assessment method for the unbiased toxicity testings of nano-materials, which minimize artifacts of the conventional methods for the toxicity assessment of the nano-materials by considering the dose characteristics of the nano-material itself using Selective multi-Plane Illumination Microcopy (SPIM); and the response characteristics of the nano-material using the improved or novel cellular responses assessment methods for nano-materials (e.g., modified MTT assay using image cytometric analysis, normal-inverted exposure apparatus, and modified flow cytometry), and a system and an apparatus thereof.
