  • Method of selecting anti-fuses and method of monitoring anti-fuses
    Patent number: 8804448
    Abstract: For selecting anti-fuses in a semiconductor memory device, a decoder block may be enabled to receive selection information for selecting the anti-fuses. The selection information is decoded in the decoder block to select at least one of the anti-fuses. Target operation is performed on the selected anti-fuses. The decoder block is disabled.
    Type: Grant
    Filed: May 2, 2012
    Date of Patent: August 12, 2014
    Assignee: Samsung Electronics Co., Ltd.
    Inventors: Ju-Seop Park, Jong-Pil Son, Sin-Ho Kim, Hyoung-Joo Kim, Je-Min Ryu, Sung-Min Seo
  • Semiconductor memory device for controlling operation of delay-locked loop circuit
    Patent number: 8730751
    Abstract: A semiconductor memory device for controlling an operation of a delay-locked loop (DLL) circuit is provided. The semiconductor memory device includes a DLL circuit that receives an external clock signal and that performs a locking operation on the external clock signal and an internal clock signal, thereby obtaining a locked state. A control unit controls the DLL circuit to constantly maintain the locked state during an updating period of an auto-refresh period of an auto-refresh operation for refreshing memory banks.
