摘要： An aspect of this invention is a method for providing a PreSET region in a memory device wherein the PreSET region includes one or more lines of the memory device which have been PreSET; performing a write operation on one or more out of place lines of the memory device by writing to the PreSET region instead of writing to an in place line of the memory device; and storing in an indirection table a mapping of each of a respective plurality of logical pages of the memory device to a corresponding physical page of a plurality of physical pages of the memory device, wherein the indirection table keeps track of the one or more out of place lines.
摘要翻译：本发明的一个方面是用于在存储器件中提供PreSET区域的方法，其中PreSET区域包括已经被PreSET存储器件的一行或多行; 通过写入PreSET区域而不是写入到存储器件的位置线来对存储器件的一个或多个不合适的行执行写入操作; 以及在所述间接表中存储所述存储器设备的相应多个逻辑页面中的每一个到所述存储器设备的多个物理页面的对应物理页面的映射，其中所述间接表保持跟踪所述存储器设备中的所述一个或多个地线。

摘要： A method for detecting memory cells that are stuck in a physical state. The method includes performing a diagnostic read of a memory cell in a memory system. The memory system is configured to utilize at least one read threshold value to determine a read data value stored in the memory cell when performing a data read operation on the memory cell. Performing the diagnostic read includes: comparing a measurement property of the memory cell to at least one diagnostic threshold value, where at least one of the diagnostic threshold values is different from all of the read threshold values; and identifying the memory cell as being stuck in a physical state based on the comparing. Based on identifying the memory cell as being stuck in a physical state, an indication that memory cell is stuck is output along with a diagnostic data value associated with the physical state.

摘要： A compression engine and method for optimizing the high compression of a content addressable memory (CAM) and the efficiency of a static random access memory (SRAM) by synchronizing a CAM with a relatively small near history buffer and an SRAM with a larger far history buffer. An input stream is processed in parallel through the near history and far history components and an encoder selects for the compressed output the longest matching strings from matching strings provided by each of the near history and far history components.

摘要： Embodiments relate to stale data detection in a marked channel for a scrub. An aspect includes bringing the marked channel online, wherein the computer comprises a plurality of memory channels comprising the marked channel and a remaining plurality of unmarked channels. Another aspect includes performing a scrub read of an address in the plurality of memory channels. Another aspect includes determining whether data returned by the scrub read from the marked channel is valid or stale based on data returned from the unmarked channels by the scrub read. Another aspect includes based on determining that the data returned by the scrub read from the marked channel is valid, not performing a scrub writeback to the marked channel. Another aspect includes based on determining that the data returned by the scrub read from the marked channel is stale, performing a scrub writeback of corrected data to the marked channel.

摘要： A compression engine and method for optimizing the high compression of a content addressable memory (CAM) and the efficiency of a static random access memory (SRAM) by synchronizing a CAM with a relatively small near history buffer and an SRAM with a larger far history buffer. An input stream is processed in parallel through the near history and far history components and an encoder selects for the compressed output the longest matching strings from matching strings provided by each of the near history and far history components. A further optimization is enabled by selectively disabling one or the other of the two types of compressors.
