20120254705 | ERROR CORRECTION DECODER AND ERROR CORRECTION METHOD THEREOF - An error correction code (ECC) decoder processing data read from a storage media includes a plurality of processing elements for detecting an error in at least one of a plurality of channel data, wherein the plurality of channel data is received via a plurality of channels, and wherein the plurality of processing elements are driven independently from the plurality of channels | 10-04-2012 |
20120284589 | MEMORY SYSTEM AND ERROR CORRECTION METHOD - Disclosed is an error correcting method which includes detecting an error of meta data having a seed used to randomize user data; correcting the error of the meta data when the error is detected from the meta data; receiving the user data based upon seed confirmation information associated with an error existence of the seed or an error correction result of the seed; detecting an error of the user data; and correcting the error of the user data when the error is detected from the user data. | 11-08-2012 |
20120290896 | MEMORY CONTROLLER AND OPERATING METHOD OF MEMORY CONTROLLER - A method of operating a memory controller to control a memory device includes reading a read vector from the memory device and correcting one or more errors in the read vector, where a power consumed at the correcting is varied according to the number of errors in the read vector. | 11-15-2012 |
20120290901 | MEMORY CONTROLLER AND OPERATING METHOD OF MEMORY CONTROLLER - A controller to control a memory system including a memory device. The controlling the memory system may include calculating an error location polynomial in a received read vector with a key equation solving unit of the memory system to read data from the memory device, estimating the number of errors in the received read vector with a control unit of the memory system according to at least one of the calculated error location polynomial and information on the error location polynomial, searching error locations of the received read vector according to the calculated error location polynomial with a chien search unit of the memory system with the control unit. A cycle-per power consumption of the chien search unit may be adjusted with the control unit. A maximum correction time may be adjusted according to the number of errors of the read vector. | 11-15-2012 |
20140181589 | MEMORY CONTROLLER AND OPERATING METHOD OF MEMORY CONTROLLER - A method of operating a memory controller to control a memory device includes reading a read vector from the memory device and correcting one or more errors in the read vector, where a power consumed at the correcting is varied according to the number of errors in the read vector. | 06-26-2014 |
20140189218 | METHOD OF PROGRAMMING DATA INTO NONVOLATILE MEMORY AND METHOD OF READING DATA FROM NONVOLATILE MEMORY - Disclosed is a method of programming data into a nonvolatile memory that includes a plurality of memory cells connected with a word line, each memory cell storing first to mth bits of a plurality of bits, the plurality of bits forming first to mth pages. The method includes generating first to mth metadata based on first to mth page data received; rearranging the first to mth metadata to generate first to mth rearranged metadata; and programming the first to mth rearranged metadata and the first to mth page data into the first to mth pages, respectively. | 07-03-2014 |
20140223228 | MEMORY SYSTEM AND ERROR CORRECTION METHOD - Disclosed is an error correcting method which includes detecting an error of meta data having a seed used to randomize user data; correcting the error of the meta data when the error is detected from the meta data; receiving the user data based upon seed confirmation information associated with an error existence of the seed or an error correction result of the seed; detecting an error of the user data; and correcting the error of the user data when the error is detected from the user data. | 08-07-2014 |
20150256197 | MEMORY SYSTEM AND ERROR CORRECTION METHOD - Disclosed is an error correcting method which includes detecting an error of meta data having a seed used to randomize user data; correcting the error of the meta data when the error is detected from the meta data; receiving the user data based upon seed confirmation information associated with an error existence of the seed or an error correction result of the seed; detecting an error of the user data; and correcting the error of the user data when the error is detected from the user data. | 09-10-2015 |
