Abstract:
The present invention relates to acryl-silicone hybrid impact modifiers, the method of their manufacture, and vinyl chloride resin compositions containing the above. The acryl-silicone hybrid impact modifier of the present invention contains a seed obtained through emulsion copolymerization of vinyl monomers and hydrophilic monomers; an acryl-silicone hybrid rubber core covering the seed in which a polyorganosiloxane rubber phase is dispersed locally onto the inner part and surface of the acrylic rubber core containing alkyl acrylate polymers and a shell covering the above rubber core and containing alkyl methacrylate polymers. Thermoplastic resins containing the above, particularly by being added to vinyl chloride resins, they have effects of granting superior impact resistance, weatherability, and high gloss.

Abstract:
In a nonvolatile memory device, a program operation is performed on a plurality of nonvolatile memory cells by programming data having a first logic state in a first group among a plurality of selected memory cells selected from the plurality of nonvolatile memory cells during a first program interval of the program operation, and thereafter, programming data having a second logic state different from the first logic state in a second group among the selected memory cells during a second program interval of the program operation after the first program interval.
Abstract:
A number of read cycles applied to a selected memory location of a memory device, such as a variable-resistance memory device, is monitored. Write data to be written to the selected memory location is received. Selective pre-write verifying and writing of the received write data to the selected memory location occurs based on the monitored number of read cycles. Selectively pre-write verifying and writing of the received write data may include, for example, writing received write data to the selected memory cell region without pre-write verification responsive to the monitored number of read cycles being greater than a predetermined number of read cycles.
Abstract:
A method programs a phase change memory device. The method comprises receiving program data for selected memory cells; generating bias voltages based on reference cells; sensing read data stored in a selected memory cell by supplying the selected memory cell with verification currents determined by the bias voltages; determining whether the read data is identical to the program data; and upon determining that the program data for one or more of the selected memory cells is not identical to the corresponding read data, iteratively applying a write current to the one or more selected memory cells.
