ABSTRACT:
The present invention concerns a method and apparatus that generally prevents an output glitch in a sense amplifier during a transition from a strong zero to a weak zero. When multiple cells are turned on, a virtual ground node is raised high due to the current flowing through the virtual ground device. A recover node is generally held close to the read product term line RPT. When a transition from a strong zero occurs, the recover node swings to VCC and provides conductance on the virtual ground node which generally eliminates the glitch.
