Abstract
A parity generation circuit includes a plurality of bit-generation circuits. Each bit-generation circuit receives respective data bits and a respective hard latch signal, and operates to generate a parity signal indicating the parity of the corresponding data bits when the hard latch signal is inactive. Each bit-generation circuit drives the parity signal to a set value when the hard latch signal is active. An output circuit is coupled to the bit-generation circuits to receive the parity signals and operates to generate an output parity signal in response to the parity signals from the bit-generation circuits.
