摘要:
An encoding device includes an encoder and a puncturing unit. The encoder generates parity bits based on information bits. The puncturing unit punctures the parity bits based on a puncturing pattern complying with a first criterion determining a period of the puncturing pattern and a second criterion determining positions of remaining parity bits.

A method for programming a flash memory cell comprises providing input data to the flash cell and providing a segmented programming pulse to the flash memory cell. The segmented programming pulse includes programming segments, each successive programming segment including a programming potential higher than the programming potential used in a previous programming segment, each programming segment followed by a zero-potential compare segment. The output of the flash memory cell is compared with the input data during the compare segment after each programming segment. The segmented programming pulse is terminated if the output of the flash memory cell matches the input data. The programming potential in each programming segment is increased during the programming segment. The programming potential in successive segments is either is increased or stepped up to the final value of the previous programming segment.

The present invention relates to a container (e.g., a bottle) for holding liquid therein. More particularly, the container includes a body having upper and lower ends and a recessed storage compartment formed in the lower end. The container also includes a plurality of cups removably positioned in the storage compartment. The storage compartment extends upwardly from the lower end toward the upper end of the body such that the storage compartment is recessed into the body. The storage compartment is sized and shaped such that the cups are housed completely within the storage compartment.

A method for fabricating an STI gap fill oxide layer in a semiconductor device is provided. The method can include: forming a shallow trench for forming an STI on a semiconductor substrate; forming an STI liner oxide layer in the shallow trench for the STI; depositing an APCVD oxide layer at an upper portion of the STI liner oxide layer for an oxide layer gap fill in the shallow trench of the STI; d) performing a densifying annealing process to densify the APCVD oxide layer; and depositing an HDP-CVD oxide layer at an upper portion of the APCVD oxide layer so that the STI shallow trench is completely gap-filled.

This invention discloses a method of manufacturing a flash EEPROM cell having a split gate structure in which source and drain regions are formed by self align method without using of an additional mask. Problems caused by that length of control gates in each cell are different from each other due to the misalignment between a mask for forming the control gate and a mask for forming source and drain regions are solved since source and drain regions are formed by self align method without using of an additional mask.

Disclosed are an LDPC encoding/decoding method and a device using same. The method includes the steps of: (a) generating an information bit sequence by determining information bits to be encoded from among a group of information bits; (b) generating a modified information bit sequence by inserting a preset error floor prevention bit into at least one preset position in the information bit sequence; (c) generating a parity check bit on the basis of the modified information bit sequence; and (d) performing encoding by using the modified information bit sequence and the parity check bit. According to the disclosed method, performance degradation of LDPC encoding and decoding due to an error floor phenomenon can be prevented.
