Latest Patents

One of Jiang's latest patents is titled "Sense amplifier local feedback to control bit line voltage." This invention describes methods for precharging bit lines using closed-loop feedback. In this embodiment, a sense amplifier includes a bit line precharge circuit that sets a bit line to a read voltage before sensing a memory cell connected to it. The precharge circuit features a first transistor in a source-follower configuration, with local feedback applied from the first source node to the first gate, which reduces the bit line settling time. The voltage applied to the first gate can vary over time based on the conductivity of the selected memory cell.

Another significant patent by Jiang is "Sensing multiple reference levels in non-volatile storage elements." This patent discloses techniques for sensing multiple reference levels in non-volatile storage elements without altering the voltage on the selected word line. The process involves determining the condition of a selected non-volatile storage element concerning a first reference level and modifying the voltage on the source terminal of the sensing transistor accordingly. This allows for efficient sensing of two different reference levels while saving dynamic power due to the low capacitance of the sensing transistor.
