Abstract
A memory device ( ) includes a memory array ( ) having storage units ( ) arranged in a plurality of rows ( ). A row decoder ( ) receives address information and determines which of the plurality of rows ( ) to enable. According to the determined row ( ), a row selector ( ) drives the storage units ( ) associated with the determined row ( ) to provide their outputs onto respective bitlines ( ) for identification by a bitline sensor ( ). If the received address information indicates an out of range address that does not identify any of the plurality of rows ( ) of the memory array ( ), an out of range decoder ( ) provides such determination to drive an out of range selector ( ) to enable storage units ( ) arranged in a single row ( ) of a bitline driver ( ). Outputs from the storage units ( ) are applied to the respective bitlines ( ) during an out of range address occurrence to prevent the bitlines ( ) from being placed in an undesirable floating state.
