Latest Patents

One of his latest patents is a "Leakage-free dummy cell for semiconductor devices." This invention provides a semiconductor device that includes a multiplexer, a master latch, and a slave latch. The multiplexer outputs an inverse of an input data signal or an inverse scan input signal according to a scan enable signal. The master latch is coupled to an output terminal of the multiplexer and is configured to latch the inverse of the input data signal based on an input clock signal when the scan enable signal is in a low-logic state. The slave latch is coupled to the output terminal of the multiplexer through a first clocked CMOS inverter and is designed to receive the input data signal, outputting a latched slave latch data based on the input clock signal. A leakage-free dummy cell is strategically placed in a non-critical path of the master latch and the slave latch.

Another notable patent is the "Data retention circuit and method." This circuit includes a first power node with a first voltage level, a second power node with a different voltage level, and a reference node with a reference voltage level. The master latch outputs a first bit based on a received bit, while the slave latch outputs a second bit based on the first bit and an output bit based on a selected one of the first bit or a third bit. A first level shifter outputs the third bit based on a complementary bit pair, and a retention latch, which includes a second level shifter and a pair of inverters, outputs the complementary bit pair based on the second bit. The slave latch and the first level shifter are coupled between the first power and reference nodes, while the retention latch is coupled between the second power and reference nodes.
