  • Patent number: 8432758
    Abstract: A device for storing error information of a memory device includes a plurality of parent memories and a plurality of child memories. Each of the parent memories stores a row address and a column address of one defective cell. Each of the child memories stores a column address of a defective cell, having a row address identical to a row address stored in the corresponding parent memory, or a row address of a defective cell, having a column address identical to a column address stored in the corresponding parent memory. Herein, each of the parent memories stores information about information about whether a row repair must be performed to repair a defective cell stored in the parent memory and information about whether a column repair must be performed to repair a defective cell stored in the parent memory.

  • Patent number: 7842125
    Abstract: Disclosed herein are a process for the refinement of nitrogen trifluoride gas and an adsorbent used therein. A nitrogen trifluoride (NF3) gas including carbon tetrafluoride (CF4) as an impurity is permeated into a bed of the zeolite 3 A, 4A or 5 A which is ion exchanged with alkali earth metal and is thermally treated at 150 to 600° C. for 0.5 to 100 hours so as to selectively adsorb nitrogen trifluoride onto the bed, followed by the desorption of the nitrogen trifluoride therefrom.
