Latest Patents

One of Ryan's latest patents is titled "Sense amplifier sleep state for leakage savings without bias mismatch." This invention addresses the issue of leakage current in sense amplifiers by implementing a biasing technique that equalizes matched transistor bias during idle states. The design includes a first read select transistor that connects a true bit line to a sense amplifier true (SAT) signal line, while a second read select transistor connects a complement bit line to a sense amplifier complement (SAC) signal line. During the precharge state, both SAT and SAC signal lines are precharged, and an equalization circuit shorts these lines. The differential sense amplifier circuit, which latches the memory cell value, is coupled to both the SAT and SAC signal lines. Importantly, the precharge circuit and the differential sense amplifier circuit are turned off during a sleep state, allowing the SAT and SAC signal lines to float. A sleep circuit is also implemented to short the SAT and SAC signal lines during this sleep state, effectively reducing leakage.
