Latest Patents

One of her latest patents is titled "Method and apparatus for programming auto shut-off." This invention discloses a method and system for enabling auto shut-off of programming in non-volatile memory cells. The system includes a memory array with multiple memory cells, each capable of storing one bit of data. During the programming process, programming signals are applied to the target memory cells. After a predefined period, the auto shut-off system begins sensing an output signal from the memory cell. Once an output signal is detected, the system waits for a second predefined period before turning off the programming voltages. The system can be configured to sense either an output voltage or an output current from the memory cell, comparing it to a reference value to determine when the cell is programmed.

Another significant patent by Cheng is focused on "Reducing bit line leakage current in non-volatile memories." This invention provides methods for minimizing leakage current in memory cells. In one embodiment, an unselected program word line is biased to a specific voltage, while in another, an unselected memory cell is biased to a negative voltage during read operations. These innovations aim to improve the performance and longevity of non-volatile memory devices.
