An integrated circuit having an SRAM cell includes a pair of cross-coupled inverters with first driver and load transistors connected to provide a first storage node and second driver and load transistors connected to provide a second storage node. A cache is established containing program code segments including library calls and application program interfaces that require security permissions at runtime. Fluid to be filtered flows through the main filter element from an upstream dirty side to a downstream clean side, and flows axially in the hollow interior. As a result, the present invention eliminates the need for separate processing stations for depositing the conductive material and cleaning the wafer. In a specific implementation, the selected keyword information is provided by an entity other than the end user.
