enable and write assist controls for the output and input datapaths respectively the time to turn on the sense amplifier 16 is about the time the bitlines have a sufficiently signal developed with this signal development 70 mv at slow corners much higher at fast corners where stability is a concern the cell is out of the danger region for stability so the read signal from timing control circuits 38 can be used as the read control input 26 to release the stability assist on the wordline wl depending upon the particular implementation a typical delay may be on the order of 100 300 ps for the write cycle write control input 26 can be derived from the write signal but delayed to be same as the read trigger would be during the read cycle to protect half selected columns during a write operation the write signal too may be used if the timing is as good fig3 depicts an illustrative timing diagram of a write operation showing the behavior of wordline wl 44 and node nt 42 fig1 after the wl assist is released i e deactivated at delay t d traces 44 u2032 and 42 u2032 depict the behaviors of the wordline wl and node nt without deactivation of the wl assist as can be seen nt 42 flips sooner relative to nt 42 u2032 when the assist is deactivated in addition it can be seen that wl 44 remains stable fig4.
