  • Patent number: 11935599
    Abstract: A fast burst program sequence that reduces overall NAND flash programming time is disclosed. The burst program sequence includes maintaining a charge pump in an ON state and not fully discharging the WL/BLs at the conclusion of the programming phase of each program operation. As a result, the fast burst program sequence provides total program time savings over an existing cache program sequence by eliminating the full WL/BL discharge and charge pump reset that conventionally occurs after each program operation, which in turn, allows for the transfer of next page data from the page buffer to the data latches to be hidden within the program time of a prior/current program operation.

  • Patent number: 6830913
    Abstract: The invention provides isolated nucleic acid molecules, designated ABCB9 transporter nucleic acid molecules, which encode novel ABC transporter family members. The invention also provides antisense nucleic acid molecules, recombinant expression vectors containing ABCB9 transporter nucleic acid molecules, host cells into which the expression vectors have been introduced, and nonhuman transgenic animals in which an ABCB9 transporter gene has been introduced or disrupted. The invention still further provides isolated ABCB9 transporter proteins, fusion proteins, antigenic peptides, anti-ABCB9 transporter antibodies, and screening assays for ABCB9 transporter modulators. Diagnostic and therapeutic methods utilizing compositions of the invention are also provided.

  • Patent number: 4837306
    Abstract: The invention provides a method for selecting hybridomas which produce antibodies specific to domains of a cell surface antigen which is usually not accessible at the surface of intact cells. The method employs the screening of the hybridoma clones obtained for the production of antibodies specific against the cell surface antigen by use of immunoblotting analysis, namely by screening the clones against antigen immobilized on a solid substrate such as nitrocellulose. The invention also includes those hybridomas and monoclonal antibodies when produced according to the method. The method provides monoclonal antibodies to P-glycoprotein surface antigen correlated with multidrug resistance. The antibodies are used to obtain a cDNA probe which in turn was used to select a cDNA clone encoding for a portion of the P-glycoprotein including the C-terminal end.
