摘要： Optical disk players include a disk spinning system that is configured to spin an optical disk at a constant linear velocity and a burst cutting area decoding system that is configured to decode data in a burst cutting area of the optical disk, while the optical disk is spinning at the constant linear velocity. The burst cutting area data decoding system may be configured to determine a rotational frequency of the optical disk while reading the data in the burst cutting area, and using the rotational frequency that was determined to decode the data in the burst cutting area that was read.

摘要： An on-the-fly error checking and correcting system and method of supporting a non-volatile memory processes data using an on-the-fly error correction method to be performed between a temporary memory and a flash memory. The flash memory stores actual data read from the temporary memory and parity generated on-the-fly in a write mode, and transmits the stored data to the temporary memory, computes a syndrome from the stored data on-the-fly, and generates an error correction information signal according to the result of computing in a read mode. Thus, error correction may only be selectively performed.
摘要翻译：一种支持非易失性存储器的即时错误检查和校正系统和方法使用将在临时存储器和闪速存储器之间执行的即时纠错方法来处理数据。闪速存储器以写入模式存储从临时存储器读取的实际数据和在运行中生成的奇偶校验，并将所存储的数据发送到临时存储器，从存储的数据运行中计算校正子，并且生成根据在读取模式下的计算结果的纠错信息信号。因此，可以仅选择性地执行纠错。

摘要： A password system includes a user interface, a password generating unit, and a password checking unit. The password generating unit generates a password including multiple frames, generates an integrity check code associated with the generated password, and scrambles the generated password and provides the scrambled password to the user interface. The password checking unit stores the integrity check code, frame number information and scramble information which are provided from the password generating unit, descrambles a scrambled password that is input from the user interface based on the stored scramble information, and authenticates the user interface by comparing an integrity check code generated from the descrambled password and the stored integrity check code.
