Patents by Inventor Stefan Wuensche

Stefan Wuensche has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7149134
    Abstract: A memory device (10) includes an array (12) of memory cells arranged in rows and columns. Preferably, each memory cell includes a pass transistor coupled to a storage capacitor. A row decoder (18) is coupled to rows of memory cells while a column decoder (14) is coupled to columns of the memory cells. The column decoder (14) includes an enable input. A variable delay (32) has an output coupled to the enable input of the column decoder (14). The variable delay (32) receives an indication (R/W?) of whether a current cycle is a read cycle or a write cycle. In the preferred embodiment, a signal provided at the output of the variable delay (32) is delayed if the current cycle is a read cycle compared to if the current cycle is a write cycle.
