Jeffrey M. Tsai has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11264099
    Abstract: An example apparatus includes a controller and a memory device. The memory device is configured to maintain, internal to the memory device, a status of a number of open blocks in the memory device. The status can include a programming operation being initiated in the respective number of open blocks. Responsive to receipt of, from the controller, a request to direct initiation of the programming operation to a word line, determine a group of memory cells associated with the word line that programs first relative to other groups of memory cells associated with the word line and maintain, included in the status of an open block, a voltage at which the group of memory cells is the first group to program.
    Type: Grant

  • Patent number: 7848151
    Abstract: A programming circuit and method to apply a controlled or predetermined voltage pulse for charge transfer to or from the floating gate of a non-volatile memory cell in an incremental manner to control the overall voltage across the gate oxide. Voltage above a transfer threshold voltage, such as above a tunneling threshold voltage, is applied in a stepwise charge transfer manner to or from the floating gate up to a voltage limit that is below the thin oxide damage threshold. Controlling the overall voltage avoids oxide breakdown and enhances reliability.
