  • Patent number: 11307065
    Abstract: An angle sensor generates an angle detection value based on a first and a second detection signal. A correction apparatus performs correction processing for generating a first corrected detection signal by adding a first correction value to the first detection signal and generating a second corrected detection signal by adding a second correction value to the second detection signal. When an angle to be detected varies with a period T and if no correction processing is performed, the angle detection value contains an Nth-order angle error component varying with a period of T/N. Each of the first and second detection signals contains an (N?1)th-order signal error component and an (N+1)th-order signal error component. The order of the first and second correction values is N?1 or N+1.

    Abstract: A memory is provided that is configured to practice both a normal read operation and also a burst mode read operation. A burst mode address comparator compares a current row address to a preceding row address from a preceding read operation to determine whether a read operation is a normal read operation or a burst mode read operation.

  • Patent number: 11264083
    Abstract: This application relates to a data protection system and protection method of a display apparatus, and the system comprises a memory, a TCON, and a switcher. The switcher selectively outputs a constant potential signal and a read/write control signal to a memory according to a potential change of a control signal. When the switcher transmits and outputs the constant potential signal to the memory, the switcher disconnects an electrical coupling between the read/write control signal and a protection control end. The memory maintains timing control data to be write-protected according to the obtained signal, or switches the timing control data to be readable-and-writable or write-protected.

  • Patent number: 11257555
    Abstract: The present invention relates to systems and methods for implementing wear leveling in a flash memory device that emulates an EEPROM. The embodiments utilize an index array, which stores an index word for each logical address in the emulated EEPROM. Each bit in each index word is associated with a physical address for a physical word in the emulated EEPROM, and the index word keeps track of which physical word is the current word for a particular logical address. The use of the index word enables a wear leveling algorithm that allows for a programming command to a logical address to result in: (i) skipping the programming operation if the data stored in the current word does not contain a “1” that corresponds to a “0” in the data to be stored, (ii) reprogramming one or more bits of the current word in certain situations, or (iii) shifting to and programming the next physical word in certain situations.
