Systems and methods for improving NAND flash memory yields by identifying memory blocks with benign word line defects. Memory blocks including word line defects may be classified as incomplete memory blocks and may be used for storing data fragments. A data fragment may correspond with data written into memory cells associated with one or more contiguous word lines within a memory block that does not include a bad word line. In some cases, firmware associated with a NAND flash memory device may identify one or more data fragments based on the location of bad word lines within a memory block. A word line defect may be considered a benign defect if the defect does not prevent memory cells connected to other word lines within a memory block from being programmed and/or read reliably.

NAND flash word line management using multiple fragment pools

Disclosed are novel methods and apparatus for provision of efficient, effective, and/or flexible computer system layout and/or cooling configuration. In accordance with an embodiment of the present invention, a method of cooling a computer system is disclosed. The computer system may include a plurality of heat generating electrical components that require cooling. The method includes: providing at least two cooling fans arranged front to back of the computer system to create a push (inlet) and pull (outlet) airflow to cool the computer system and providing a plurality of temperature sensors located at various locations within the computer system to sense a local temperature.

Computer system layout and cooling configuration

According to one embodiment, a computer system is disclosed. The computer system includes a circuit board, and connectors mounted on the circuit board. Each connector supports a peripheral component interface (PCI) card. In addition, the computer system includes a shroud that encloses the connectors in order to separate the associated PCBs from other components on the circuit board.
