摘要:
Methods of performing a read retry, including reading a non-volatile memory with new read parameters, and devices for performing such methods are disclosed. The read retry operation and/or subsequent read retry operation may be initiated and/or completed before it is determined that such read retry operation is warranted. For example, a page of a NAND flash memory may be read in a read retry operation with new read voltage levels applied to a word line of the page. For example, a read retry operation may be performed on a target page prior to determining errors of a previous read page of data of the target page are uncorrectable via an ECC operation.

A method for operating a memory controller capable of controlling a maximum count of a read retry operation is disclosed. The method includes programming a first real time clock (RTC) value indicating a time-of-day when a program operation is performed when the program operation for programming a data to a storage region of a non-volatile memory, obtaining information for the storage region by using the first RTC value read from the non-volatile memory and a second RTC value indicating a time-of-day when a read operation is performed, when the read operation for the data programmed to the storage region is performed, and decreasing a maximum count of a read retry operation by using the information, when the read retry operation is performed for the storage region.

A display substrate includes a pixel electrode including a main electrode and a sub-electrode disposed apart from the main electrode and including an opening part. The display substrate includes a first switching device and a second switching device. The first switching device is connected to the main electrode. An extension electrode extends from the second switching device and overlaps the opening part. The extension electrode is connected to the sub-electrode via a contact part. According to the present invention, after a defective pixel is repaired, the repaired pixel operates normally.

A command scheduling method and apparatus for reducing the complexity of a virtual file system embodied in a nonvolatile data storage device and performing efficient interleaving by setting a preparation phase of a command schedule in the virtual file system embodied in the nonvolatile data storage device is provided. The method includes setting a preparation phase in which a plurality of metadata commands for data management are executed, and if the plurality of metadata commands are completely executed in the preparation phase, executing data read/write commands. Accordingly, by simplifying the scheduling structure of the virtual file system (FTL), code size and resource use can be reduced. In addition, by performing exact interleaving, burst data transmission between a host and a memory storage device can be achieved even without using a large capacity buffer.

Disclosed are an apparatus and a method for storing and managing additional data in a file system. The apparatus comprises a search unit to search for an unused region in a directory entry, a storage unit to store additional data in the unused region, and an additional data managing unit to locate the position of the additional data using the signature and checksum of the additional data. The method includes (a) searching for an unused region of a directory entry, (b) storing additional data in the unused region, and (c) locating the position of the additional data using the signature and checksum of the additional data. According to the present invention, additional data can be stored, used and managed utilizing unused regions of a directory entry without degrading the compatibility of the file system, and enhancing the performance of the FAT file system.
