  • Patent number: 10083764
    Abstract: A memory system includes a memory controller, a memory cell array, a location information storage unit, an address mapping table, an address conversion unit, and a mapping information calculation unit. The memory controller generates a logical address signal and an address re-mapping command. The memory cell array includes a plurality of logic blocks. The location information storage unit stores location information corresponding to faulty memory cells included in the memory cell array. The address mapping table stores address mapping information. The address conversion unit converts the logical address signal to a physical address signal corresponding to the memory cell array based on the address mapping information. The mapping information calculation unit generates the address mapping information to reduce the number of logic blocks including the faulty memory cells based on the location information upon the mapping information calculation unit receiving the address re-mapping command.

  • Patent number: 10035902
    Abstract: Provided are a resin blend for melt processing, a pellet and a method of preparing a resin article using the same. The resin blend may include a first resin, and a second resin having a difference in melt viscosity from the first resin of 0.1 to 3000 pa*s at a shear rate of 100 to 1000 s?1 and a processing temperature of the resin blend. The resin blend can improve mechanical and surface characteristics of a resin article. Further, since coating or plating is not required for manufacturing a resin article, a manufacturing time and/or cost can be reduced, and productivity can be increased.
