Abstract:
A solar cell is provided with a hetero-junction front structure (e.g., P/N or P/I/N) and is further provided in a back portion of thereof with a passivation layer having a plurality of openings defined therethrough. A BSF-forming binder material and a back face electrode are provided contacting the back surface and are fired to thereby bind the back face electrode to the structure and to form a BSF region extending from the openings of the passivation layer.

Abstract:
A non-volatile memory device includes a feedback circuit and a precharge switching transistor. The feedback circuit generates a feedback signal based on a voltage level of a bitline during a precharge operation. The precharge switching transistor, in response to the feedback signal, controls a precharge current for precharging the bitline. The speed of the precharge operation may be increased and/or mismatch of the bias signals in precharging a plurality of bitlines may be reduced.
Abstract:
A nonvolatile memory system is operated by performing a program loop on each of a plurality of memory cells, each program loop comprising at least one program-verify operation and selectively pre-charging bit lines associated with each of the plurality of memory cells during the at least one program-verify operation.
Abstract:
A flash memory device controls a common source line voltage and performs a program verify method. A plurality of memory cells is connected between a bit line and the common source line. A data input/output circuit is connected to the bit line and is configured to store data to be programmed in a selected memory cell of the plurality of memory cells. The data input/output circuit maintains data to be programmed within the data input/output circuit during a program verify operation, and decreases noise in the common source line by selectively precharging the bit line based on the data to be programmed.
