错误校正码

ECC (Error Correcting Code) memory includes an additional memory chip which allows the motherboard to detect and correct one bit errors.

ECC（错误校正码）内存包含一个额外的内存芯片，允许主板检测和纠正一位错误。

Adata Micro SDCH flash card offers automatic way for detecting and correcting errors that occur while transferring files using Error Correcting Code (ECC) facility.

Adata Micro SDCH闪存卡提供自动检测和纠正使用错误校正码（ECC）设备传输文件时发生的错误。

During the Beginning of Life (BOL) and End of Life (EOL) of the NAND Flash, these bit errors are then detected and corrected by the embedded Error Correcting Code (ECC) component.

在 NAND 闪存的使用寿命开始（BOL）和使用寿命结束（EOL）期间，这些位错误随后会被嵌入式错误校正码 （ECC）组件检测到并修复。

In the related-art technology described above, two types of sizes of units in which access is allowed are arranged in order to execute error detection and correction processing in each of the sizes. However, because this related-art technology generates, in the random access bank, an error correcting code in a data unit smaller than that of the sequential access bank, a capacity occupied by error correcting codes gets relatively large, thereby causing a problem of the deteriorated efficiency of capacity. In this case, if the storage capacity in the random access bank runs short, it is necessary to move part of the data to the sequential access bank, thereby causing a problem of lowered system performance. Generally, in terms of bit cost, the random access bank is several times as large as the sequential access bank, so that increasing the capacity of the random access bank directly increases the system cost.

在上述相关领域的技术中，设置了允许存取的两种单位尺寸，以在每种尺寸内执行错误检测和校正处理。但是，由于该相关领域的技术在随机存取库中以小于顺序存取库的数据单位的数据单位生成错误校正码，错误校正码占据的容量相对较大，从而造成容量效率降低的问题。这种情况下，如果随机存取库中的存储容量不足，需要将一部分数据移动到顺序存取库中，从而造成系统性能降低的问题。一般来说，随机存取库的位成本是顺序存取库的几倍，因此随机存取库容量的增加直接增加了系统成本。

By deliberately devising a binary image as the watermark, we introduced an error correcting code watermarking scheme, and applied it to the traditional embedded zerotree wavelet(EZW) watermarking algorithm.

通过对二值水印图像进行精心设计，引入纠错编码机制，并将其应用于传统的小波零树（EZW ）算法中。

It is a general practice, with the nonvolatile memories mentioned above, to execute error detection and correction processing based on ECC (Error Correcting Code) in order to improve the data retention characteristics. To be more specific, at the writing of data, an error correcting code is computed and the computed error correcting code is recorded to a nonvolatile memory along with the data, and, at the time of reading the data, the data and the error correcting code are read at the same time for bit error detection and correction processing. Assuming the error detection and correction processing like this makes it clear that the matching the unit of error correcting code with the unit of access to a nonvolatile memory is advantageous in performance. If no match is found between both the units, the error detection and correction processing based on an error correcting code is executed, so that a portion other than the data requested for access must also be read, thereby increasing the overhead in access processing.

上述非易失性存储器的一般惯例是，根据ECC（错误检测码）执行错误检测和校正处理，以提高数据保持特性。更加具体地说，在写入数据时，计算错误校正码，并将计算的错误校正码与数据一起存储在非易失性存储器内，在读取数据时，同时读取数据和错误校正码，用于误码检测和校正处理。从这种错误检测和校正处理可明显看出，错误校正码的单位与非易失性存储器存取单位的匹配对性能有利。如果两个单元之间没有发现匹配，根据错误校正码执行错误检测和校正处理，使除存取所需的数据之外的部分也必须被读取，从而增加存取处理的开销。

The first ECC generation block 220 generates a first error correcting code (ECC) for the data held in the data buffer 210 in a write operation. The first ECC generated by the first ECC generation block 220 is stored in the NVM 300 as related with the data. Therefore, it is desired that this first ECC be an error correcting code for encoding on an access basis in the NVM 300. In addition, a BCH code may be used for the first ECC. It should be noted that, because an error correcting code has a function of error detection, the error correcting code may also be referred to as an error detection code. It should be noted that the first ECC generation block 220 is one example of a first error detection code generation block cited in the scope of claims herein.

ﾋﾚﾒｻECC生成块220为写入操作中保留在数据缓冲器210中的数据生成第一错误校正码（ECC）。ﾋﾚﾒｻECC生成块220生成的第一ECC存储于与所述数据相关的NVM 300中。因此，该第一ECC应为用于基于存取编码到NVM 300中的错误校正码。另外，BCH编码可用于第一ECC。应注意的是，由于错误校正码具有错误检测的功能，所述错误校正码还可称为错误检测码。应注意的是，所述第一ECC生成块220是本文的权利要求的范围内所述的第一错误检测码生成块的一个示例。

The higher error rate necessitates an error correcting code (ECC) that can correct multiple bit errors; for example, the SandForce SF-2500 Flash Controller can correct up to 55 bits per 512-byte sector with an unrecoverable read error rate of less than one sector per 1017 bits read.

例如，SandForce SF-2500闪存控制器可以纠正每个512字节扇区中最多55位元，从而使不可恢复读错误的发生率低于每读写1017位元时一个扇区。

ECC stands for "Error Correcting Code". It is one kind of error correction and encryption-decryption algorithm. ECC technology can greatly improve the reliability of SSD. It the the prerequisite for Nand Flash to be used normally.

ECC是"Error Correcting Code"的简写，中文名称是"错误检查和纠正"，是一种差错检测和修正算法（也是加密算法）。ECC这将使整个电脑系统在工作时更趋于安全稳定。
