ABSTRACT:
A latch (40) has a clocked feedback path (46) which performs a static latching function while using less power. The latch includes a feedback device (46) which is selectively decoupled from a feed-forward portion (42, 44) of the latch. In a normal mode of operation when the latch will be clocked often, the feedback device of the latch is not enabled and the latch effectively functions as a dynamic latch. When the latch becomes inactive for an extended period of time, the feedback device is again enabled and the latch is able to store a data value indefinitely.
