摘要： The present invention is directed to a system and method which manages one or more errors in a plurality of elements. The invention tests an element of the plurality of elements and detects the error in one of the elements. The invention then repairs a group of N elements, wherein N is greater than one and the group of N elements includes the element with the error. The invention inhibits subsequent repairs of the group of N elements.

摘要： The present invention incorporates built-in self test and self repair functionality into a semiconductor memory device in which reconfiguration data used to replace faulty memory is stored at the same time testing to identify other faulty memory cells continues. To avoid access contention conflicts to a content addressable memory used to identify rows or groups of rows having faulty memory cells, the built in test function writes test data to each cell at least twice before reading the stored data. By writing twice before reading, contention problems caused by simultaneous updating of the content addressable memory are avoided. That is, even if the content addressable memory is initially unavailable to process address information used to access a memory cell to be tested, repetition of the write process ensure that the data will be properly stored when the memory again becomes available after being updated.
摘要翻译：本发明将内置的自检和自修复功能集成到半导体存储器件中，其中用于替换故障存储器的重新配置数据被同时存储在测试中以识别其他故障存储器单元继续。为了避免将访问冲突与用于识别具有故障存储单元的行或组的行的内容可寻址存储器进行访问冲突，内置测试功能在读取存储的数据之前至少将测试数据写入每个单元格至少两次。在阅读之前两次写入，避免了同时更新内容可寻址存储器引起的争用问题。也就是说，即使内容可寻址存储器最初不可用于处理用于访问待测试的存储器单元的地址信息，所以写入过程的重复确保当存储器在更新之后再次变得可用时，数据将被适当地存储。

摘要： The present invention includes a system and a methodology for eliminating faulty memory cells in a memory array with replacement columns of memory cells and replacement rows of memory cells. The individual memory cells are checked to ensure that each is operational. Non-operational cells are replaced by first replacing columns which contain a threshold number of non-operational cells with spare columns and second removing any remaining non-operational cells by replacing the rows containing those non-operational cells with spare rows.

摘要： A method for controlling data flow to a pair of storage devices includes receiving at least one new entry to store in a first storage device or a second storage device in the pair of storage devices and determining a number of entries made to the first and second storage devices out of the at least one new entry. The method also includes calculating a difference between available space in the first storage device and the second storage device, and calculating a number of credits used by the at least one new entry based on the numbers of entries to the first and second storage devices and on the difference in available space.

摘要： A method and system for detecting and correcting a bad bit error in a solid-state nonvolatile memory device. The device includes a bad bit detection module that receives an old page from the memory device and determines whether a page has a bad bit. The device further includes a bad bit correction module that generates a new page, determines a location of the bad bit, determines a preferred value of the bad bit, determines a user value of the bad bit and inserts the preferred value into a string of bits corresponding to substantive data of the old page, recording the string of bits with the preferred value inserted therein and stores the new page at an address of the old page.
