Patent number: 8432758Abstract: 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.Type: GrantFiled: December 30, 2010Date of Patent: April 30, 2013Assignee: Hynix Semiconductor Inc.Inventors: Woo-Sik Jeong, Kang-Chil Lee, Jeong-Ho Cho, Kyoung-Shub Lee, Il-Kwon Kang, Sungho Kang, Joo Hwan Lee
