摘要： A method and apparatus for compressing and decompressing electronic documents, with maximum intradocument independence, and maximum flexibility in optimization of compression modes. The method includes receiving documents containing unknown combinations of a plural data types, including combinations of scanned data, computer rendered data, compressed data and/or rendering tags; dividing the received image into strips of blocks determining from the image itself, which data types are present in each block; compressing data of each data type present in each block with a compression method optimized for its data type. Scanned data may be further segmented into plural scanned data types, where each data type is compressed in said compressing data step with a compression method optimized for said scanned image data type. If the received data type is compressed data, the process may include the additional functions of determining a compression ratio thereof, and accepting the compressed data for use as, or decompressing and recompressing the data, based on acceptability of said compression ration determination. An instruction set is generated that allows detailed decompression instruction data and image data to be combined with transmitted compressed data. A data structure is shown, which segregates data types and instruction data, and allows for block to block and strip to strip processing independence.

摘要： Multi-bit flash memory devices are provided. The multi-bit flash memory device includes an array of memory cells and a page buffer block including page buffers. Each of the page buffers has a single latch structure and performs a write operation with respect to memory cells according to loaded data. A buffer random access memory (RAM) is configured to store program data provided from an external host device during a multi-bit program operation. Control logic is provided that is configured to control the page buffer block and the buffer RAM so that program data stored in the buffer RAM is reloaded into the page buffer block whenever data programmed before the multi-bit program operation is compared with data to be currently programmed. The control logic is configured to store data to be programmed next in the buffer RAM before the multi-bit program operation is completed.

摘要： Methods of executing a multi-page copyback program in a non-volatile memory device are provided, where the non-volatile memory device includes a memory having a plurality of memory blocks. A page of data of the memory block having a first address is replaced responsive to a generated multi-page copyback program command. It is determined if the first address of the page of data is the same as a stored address of the page at which the failure was detected. The first address is incremented if it is determined that the first address and the stored address are not the same. The pages of data are replaced, the addressed are compared and the addresses are incremented until it is determined that the incremented address and the stored address are the same. Related devices and systems are also provided herein.

摘要： A method and system are provided for producing a print that substantially corresponds to the colorimetric attributes of a corresponding proof for an electronic source file. The method and system entail creating a first raster file corresponding to the electronic source file and a second raster file corresponding to the proof. The first and second raster files are aligned to insure a spatial correlation, and a color conversion data structure is built by comparing the aligned first and second raster files. The color conversion data structure is then used to convert the first raster file to a color converted output file. The color converted output file is color transformed to an output file which is then used to produce the print. The print substantially corresponds to the colorimetric attributes of the corresponding proof for the electronic source file.

摘要： Semiconductor memory devices include a memory array having a plurality of multi-column memory blocks therein and a multi-column redundant memory block. A redundancy column selecting unit is provided, which is configured to route data read from the multi-column redundant memory block to a redundant data line, in response to a column address. A data input/output unit is also provided. This data input/output unit is connected to the redundant data line and a data line associated with a defective column in the memory array. The data input/output unit is configured to respond to an instruction to read first data from a defective column in the memory array by routing first data read from a selected redundant column in the multi-column redundant memory block to an input/output bus while concurrently blocking data read from the defective column from being transferred to the input/output bus.
