  • Publication number: 20130301358
    Abstract: A system for erasing non-volatile storage system that reduces the voltage across the transistor that interfaces between the sense amplifier and the bit line so that the transistor can be made smaller. Additionally, the use of the lower voltage allows for various components to be positioned closer to each other. The use of smaller components and smaller spaces between components allows the non-volatile storage system to include more memory cells, thereby providing the ability to store more data.

  • Patent number: 8557629
    Abstract: Disclosed is a semiconductor device having overlapped via apertures formed in an encapsulant to outwardly expose solder balls. When different types of semiconductor devices are electrically connected to the solder balls through the overlapped via apertures, flux or solder paste is unlikely to contact sidewall portions of the overlapped via apertures. Therefore, different types of semiconductor devices can be mounted with improved efficiency.

  • Patent number: 8536845
    Abstract: In a low drop out (LDO) regulator and a semiconductor device including the LDO regulator, the LDO regulator regulates a power supply voltage and applies the regulated power supply voltage to a load. The LDO regulator comprises: an output node connected to the load; a pass transistor that applies a power supply voltage to the output node; and a controller that generates a load enable signal enabling the load by delaying a regulator enable signal by a first delay time, and that increases a gate voltage of the pass transistor after receiving the regulator enable signal to thereby reduce a current flowing through the pass transistor.

  • Patent number: 8525318
    Abstract: Disclosed are a semiconductor device capable of efficiently radiating heat of a semiconductor die and a method of fabricating the same. The semiconductor device efficiently radiates the heat by preventing an encapsulant from reaching the semiconductor die by an encapsulant dam so that an upper surface of the semiconductor die is exposed out of the encapsulant. In addition, the semiconductor device is configured to expose a pre-solder ball or a conductive pattern of a substrate through a via of the encapsulant. Therefore, electrical connection between the pre-solder ball and a solder ball of another semiconductor device stacked thereon is easily achieved.

  • Publication number: 20120297245
    Abstract: Column based defect management techniques are presented. Each column of the memory has an associated isolation latch or register whose value indicates whether the column is defective, but in addition to this information, for columns marked as defective, additional information is used to indicate whether the column as a whole is to be treated as defective, or whether just individual bits of the column are defective. The defective elements can then be re-mapped to a redundant element at either the appropriate bit or column level based on the data. When a column is bad, but only on the bit level, the good bits can still be used for data.

  • Patent number: 8228729
    Abstract: Techniques for the reading and writing of data in multi-state non-volatile memories are described. Data is written into the memory in a binary format, read into the data registers on the memory, and “folded” within the registers, and then written back into the memory in a multi-state format. In the folding operation, binary data from a single word line is folded into a multi-state format and, when rewritten in multi-state form, is written into a only a portion of another word line. A corresponding reading technique, where the data is “unfolded” is also described. A register structure allowing such a “folding” operation is also presented. One set of embodiments include a local internal data bus that allows data to between the registers of different read/write stacks, where the internal bus can used in the internal data folding process.
