摘要： A fault-tolerant magnetoresistive solid-state storage device (MRAM) in use performs error correction coding and decoding of stored information, to tolerate physical defects. At manufacture, the MRAN device is tested to confirm that each set of storage cells is suitable for storing ECC encoded data, using either a parametric evaluation (step 602), or a logical evaluation (step 603) or preferably a combination of both. Failed cells are identified and a count is formed, suitably in terms of ECC symbols 206 that would be affected by such failed cells (step 604). The count can be compared to a threshold (step 605) to determine suitability of the accessed storage cells and a decision made (step 606) on whether to continue with use of those cells, or whether to take remedial action.

摘要： A magnetoresistive solid-state storage device (MRAM) employs error correction coding (ECC) to form ECC encoded stored data. In a read operation, parametric values are obtained from storage cells 16 of the device and compared to ranges to establish logical bit values, together with erasure information. The erasure information identifies symbols 206 in a block of ECC encoded data 204 which, from the parametric evaluation, are suspected to be affected by physical failures of the storage cells 16. Where the position of suspected failed symbols 206 is known from this erasure information, the ability of a decoder 22 to perform ECC decoding is substantially enhanced.

摘要： In a data storage and retrieval system, a method and system for exchanging operation parameters between a data storage device and a storage device controller is disclosed. A memory device within the data storage device comprises operation parameter registers, which store operation parameters that are indicative of environmental conditions and characteristics of the memory device itself. The operation parameter registers may be readable and writable. To initiate an exchange of operation parameters, the storage device controller sends a command code indicative of an operation parameter exchange command and designates an address in the operation parameter registers to which operation parameters are to be written or from which operation parameters are to be read.

摘要： The present invention relates to a storage device controller for controlling the operations of the data storage system. The controller includes error-correcting code (ECC) coding and decoding of data stored on media of the data storage system. A Verify procedure of the present invention is performed which verifies the validity of the data written to the media. The Verify procedure runs continuously until an error is detected or until an external event terminates the procedure. By accessing a range of memory addresses in the media and by resetting an address counter to a start of the range of addresses after a last address of the range has been accessed, the Verify procedure continuously checks the memory locations for errors. The range of addresses may include all of the accessible addresses in the data storage device. Additionally, information on the quality of the media may be collected and used to determine how much the media deteriorates over time. Sparing of defective memory locations may also be provided, even after manufacturing and packaging of the data storage system.

摘要： Byte-swapping in a buffer memory system utilizes a byte-swapping register to avoid wasteful unused buffer memory spaces that may result from a data transfer of partial word data, i.e., bytes of data less than the number of bytes in a word, to the buffer memory. When a data transfer request, e.g., a write request, requires a transfer of a partial word, the partial request is written to a word in the buffer memory, and is also stored in the byte-swapping register. In a subsequent data transfer request, the partial word stored in the byte-swapping register is combined and concatenated with sufficient bytes of data of the subsequent data transfer request to produce a complete word. The complete word is written in the word in the buffer memory, replacing the previously stored partial word, and thus fills the previously unused buffer memory space.
摘要翻译：缓冲存储器系统中的字节交换利用字节交换寄存器来避免浪费的未使用的缓冲存储空间，这些空间可能是由于部分字数据的数据传输，即数据字节数字小于单词中的字节数，缓冲存储器当数据传输请求（例如写入请求）需要传送部分字时，部分请求被写入缓冲存储器中的字，并且还存储在字节交换寄存器中。在随后的数据传输请求中，存储在字节交换寄存器中的部分字被组合并与后续数据传送请求的足够数据字节连接以产生完整字。将完整的单词写入缓冲存储器中的单词，替换先前存储的部分单词，从而填充以前未使用的缓冲区内存空间。
