PROBLEM TO BE SOLVED: To provide an improved system and method for applying a re-distributed metal layer in an integrated circuit chip. SOLUTION: The re-distributed metal layer 260 is formed of the last metal layer in an integrated circuit in the manufacturing period of the integrated circuit before final passivation is applied. This last metal layer provides a part for a solder bump pad to be used for flip chip interconnection. The re-distributed metal layer may be stuck on (1) a flat layer stuck on the second metal layer from the last through an aperture in a dielectric layer, or (2) an array configured of a via connected to the second metal layer from the last.

Abstract:
PROBLEM TO BE SOLVED: To provide a method for preserving charge of a battery as well as protecting electrical devices, and to provide an integrated circuit. SOLUTION: A maximum and a minimum battery voltage values at an output port are stored in a memory. A steady-state battery voltage at the output port is measured and stored in the memory. A processor compares the measured steady-state battery voltage with the maximum and the minimum battery voltage values. When the measured steady state battery voltage value is greater than the maximum battery voltage value, overvoltage state is reported by the processor. When the measured steady-state battery voltage value is smaller than the minimum battery voltage value, low battery voltage state is reported by the processor. COPYRIGHT: (C)2009,JPO&INPIT

PROBLEM TO BE SOLVED: To provide an improved very long instruction word processor with sequence control. SOLUTION: During each cycle, this processor generates control signals to functional units based on the values in fields of an instruction. Each instruction may include an iteration count specifying the number of cycles for which the control signals should be generated based on that instruction. The instruction set further includes flow control instructions enabling repetitive execution of a single instruction, repetitive execution of a block comprising a plurality of instructions or branching within a program. Such a processor can be used in connection with a disk controller for a hard drive of a computer. The flexible sequencing allows a hard-drive controller to be readily reprogrammed for use in connection with different types of media or to be dynamically reprogrammed upon detection of a disk read error to increase the ability of the disk controller to recover data from a disk.
