(4) Continuances exceeding 180 days from the date of arraignment may be granted by the trial court as follows:

(7) A dismissal for lack of a speedy trial under this rule shall not bar the state from again prosecuting the defendant for the same offense unless the defendant made a written demand for a speedy trial or can demonstrate prejudice from the delay.
