Recently filed patent applications of Sandisk Technologies Inc. in USPTO?

Publication number: US20180316324A1
Application number: 15/497,232

Apparatuses, systems, and methods are disclosed for offset trimming for differential amplifiers. An apparatus includes a differential amplifier. A differential amplifier includes a non-inverting input, an inverting input, and an output coupled to the inverting input via a voltage divider. A first variable current source is coupled to a non-inverting input, so that increasing a current from the first variable current source increases a voltage at the non-inverting input. A second variable current source is coupled to an inverting input, and to an output via a voltage divider, so that increasing a current from the second variable current source decreases a voltage at the output.

Publication number: US20170287568A1
Application number: 15/084,100

Systems and methods for detecting program disturb and for programming/reading based on the detected program disturb are disclosed. Program disturb comprises unintentionally programming an unselected section of memory during the program operation of the selected section of memory. To reduce the effect of program disturb, the section of memory is analyzed in a predetermined state (such as the erase state) for program disturb. In response to identifying signs of program disturb, the voltages used to program the section of memory (such as the program verify levels for programming data into the cells of the section of memory) may be adjusted. Likewise, when reading data from the section of memory, the read voltages may be adjusted based on the adjusted voltages used for programming. In this way, using the adjusted programming and reading voltages, the effect of program disturb may be reduced.
