Latest Patents

One of Jiawei Xu's latest patents focuses on a non-volatile memory with an early ramp for improved performance. This innovation aims to enhance the performance of non-volatile storage apparatus by reducing the time required for program verification. By eliminating a pause in the raising of word line voltages, the design allows for quicker discharge of memory cell channels. To compensate for the removal of this pause, the source line voltage is lowered earlier than in previous designs, ensuring that the source line reaches the necessary voltage for sensing before applying the verify reference voltage.

Another notable patent involves memory cell sensing by charge sharing between sensing nodes. This method includes pre-charging a first and second sense node, followed by discharging the second node to initiate charge sharing. The result is an improved sense margin, which enhances noise immunity and provides more accurate sensing results. The sensing circuitry described in this patent may incorporate various pre-charge circuits, sense enable circuits, and charge-sharing circuits.
