  • Memory cell having increased capacitance via a local interconnect to gate capacitor and a method for making such a cell
    Patent number: 5844836
    Abstract: A static random access memory (SRAM) cell having increased cell capacitance at the storage nodes utilizes a capacitive structure. The capacitive structure includes a dielectric material between polysilicon conductive lines and tungsten local interconnects. The polysilicon plates are each connected to drains of lateral transistors associated with the SRAM cell. A dielectric material such as silicon dioxide may be deposited between the local interconnect and polysilicon conductive lines. The capacitor structures are provided between first and second N-channel pull down transistors associated with the SRAM cell.

  • Memory device using a reduced word line voltage during read operations and a method of accessing such a memory device
    Patent number: 5796651
    Abstract: A memory device uses a reduced word line voltage during READ operations. The memory device includes a memory cell and a pass transistor for accessing the cell. The cell includes a storage node coupled to a pull-down transistor having substantially the same conductivity as the pass transistor. A drive circuit generates a reduced word line voltage to activate the pass transistor during a READ operation. The reduced word line voltage has a magnitude less than the magnitude of the bias voltage used to activate the pull-down transistor.
