摘要:
A method of encoding multi-bit level data includes: determining a range of an error pattern generated according to a transmission symbol, encoding an M-bit level of a P-bit level corresponding to the transmission symbol based on the range of the error pattern, and excluding encoding of a P-M bit level of the P-bit level. The variable P is a natural number of a value at least two, and the variable M is a natural number less than P.
摘要:
The present invention relates to a sales management system using a text recognition technique, including a business card input device for inputting a business card of a customer; a text recognition server for recognizing and classifying information of the inputted business card; a customer database (DB) for storing the classified information; a sales process presentation server for fetching the information from the customer DB and presenting each step of a sales process corresponding to the retrieved information; a sales management server for, when the steps of the sales process presented by the sales process presentation server are selected, sequentially performing the steps and storing a result of the execution in a result DB; an obstacle factor DB for storing reasons for which the sales process is not sequentially performed in the sales management server; the result DB for storing a sales management result; a result report server for transmitting the sales management result, stored in the result DB, to a superior terminal; and a superior terminal for receiving a report on the sales management result and writing an opinion on the sales management result.
摘要:
A method of programming a nonvolatile memory device comprises counting a number of state pairs in a unit of input data, modulating the unit of input data to reduce the number of state pairs contained therein, and programming the modulated unit of input data in the nonvolatile memory device. Each state pair comprises data with a first state and designated for programming in a memory cell connected to a first word line, and data with a second state and designated for programming in a memory cell connected to a second word line adjacent to the first word line. The memory cell connected to the first word line is adjacent to the memory cell connected to the second word line.
摘要:
An apparatus and a method for reading from a non-volatile memory whereby soft decision data is used to determine the reliability of hard decision data. The hard decision data read from the non-volatile memory is de-randomized and the soft decision data read from the non-volatile memory is not de-randomized. Using the soft decision data, the hard decision data is decoded.
摘要:
A data processing device which includes a conversion circuit and a pseudo random number generator including a series connection of plural shift registers. The conversion circuit receives a pseudo random number sequence from an output of one of the plural shift registers excluding a last shift register of the series connection, and converts first data to second data using the received pseudo random number sequence.
