A bit line spacer is formed with an oxide film, thereby reducing a parasitic capacitance. A storage node contact is formed to have a line type, thereby securing a patterning margin. A storage node contact plug is formed with polysilicon having a different concentration, thereby reducing leakage current.Type: GrantFiled: September 26, 2013Date of Patent: October 21, 2014Assignee: SK Hynix Inc.Inventor: Se In Kwon

Patent number: 8853761Abstract: A nonvolatile memory (“NVM”) bitcell with one or more active regions capacitively coupled to the floating gate but that are separated from both the source and the drain. The inclusion of capacitors separated from the source and drain allows for improved control over the voltage of the floating gate. This in turn allows CHEI (or IHEI) to be performed with much higher efficiency than in existing bitcells, thereby the need for a charge pump to provide current to the bitcell, ultimately decreasing the total size of the bitcell. The bitcells may be constructed in pairs, further reducing the space requirements of the each bitcell, thereby mitigating the space requirements of the separate capacitor/s. The bitcell may also be operated by CHEI (or IHEI) and separately by BTBT depending upon the voltages applied at the source, drain, and capacitor/s.Type: GrantFiled: January 30, 2012Date of Patent: October 7, 2014Assignee: Synopsys, Inc.Inventor: Andrew E.
