摘要： In a nonvolatile memory array, blocks that contain only obsolete data are modified by adding charge to their cells, increasing the charge level from the programmed charge levels that represented obsolete data to elevated charge levels. The increase in overall charge in such blocks lessens the tendency of such blocks to impact data retention in neighboring blocks.

摘要： Systems and methods are disclosed to reduce the number of partial logical groups that are erased by writing erase patterns to memory in a non-volatile memory system. When a non-aligned erase command is received, the logical addresses of data associated with the erase command may be marked as erased. If the logical group corresponds to the size of a physical metablock, the controller may also issue a physical erase command for complete logical groups within the erase command. For those parts of the erase command that encompass only partial logical groups, the ranges of the logical block addresses marked for erasure are stored. As subsequent erase commands are received the address ranges of the erase commands are added to the previously stored address ranges. When a set of erase commands spans an entire logical group, the logical group is marked for physical erasure in its entirety.
摘要翻译：公开了系统和方法，以通过将擦除模式写入非易失性存储器系统中的存储器来减少擦除的部分逻辑组的数量。当接收到不对准的擦除命令时，可以将与擦除命令相关联的数据的逻辑地址标记为擦除。如果逻辑组对应于物理元区块的大小，则控制器还可以对擦除命令内的完整逻辑组发出物理擦除命令。对于仅包含部分逻辑组的擦除命令的那些部分，存储标记为擦除的逻辑块地址的范围。随着接下来的擦除命令被接收，擦除命令的地址范围被添加到先前存储的地址范围。当一组擦除命令跨越整个逻辑组时，逻辑组被整体标记为物理擦除。

摘要： A bracket retainer is provided for securing an adapter card in a computer chassis in manner that maintains the electrical and the mechanical stability of the computer chassis and adapter card. This bracket retainer approach secures the adapter card to the computer chassis by utilizing a rotating door structure that allows the adapter card to be tightened into its card connector, as a rear tab of the adapter card, which is protruding through an opening of a rear panel of the computer chassis, is engaged by the rotating door structure. This bracket retainer approach also allows the bracket retainer to be secured to the computer chassis by interlocking the door structure with a top cover of the computer chassis.

摘要： An embedded system comprising a CPU and non-volatile memory is adapted to extend the endurance of the non-volatile memory through the use of an encoding of information stored in the non-volatile memory. One or more data bits are encoded into a larger number of non-volatile memory bit patterns such that changes to the data bits are distributed across fewer changes per non-volatile memory bit. Non-volatile memory endurance is extended since more changes to the data values are possible than can be supported by underlying changes to individual non-volatile memory bits. Word pre-erase, if present, can be accommodated as well as memory bit failures.

摘要： The embodiments described herein generally use a challenge to protect a removable mobile flash memory storage device, where the challenge may be in the form of a “Completely Automated Public Turing Test to Tell Computers and Humans Apart” (“CAPTCHA”). In one embodiment, a method is provided in which a removable mobile flash memory storage device receives a command from a host device, generates a CAPTCHA challenge, provides the CAPTCHA challenge to the host device, receives a response to the CAPTCHA challenge from the host device, determines if the response satisfies the CAPTCHA challenge, and performs the command only if the response satisfies the CAPTCHA challenge. In another embodiment, a removable mobile flash memory storage device is provided for performing these acts.

摘要： In a non-volatile memory (NVM) device having a controller and a non-volatile memory array controlled by the controller a voltage supervisor circuit monitors an output of a voltage supply powering the NVM device. The voltage supervisor circuit may be part of the NVM device or coupled to it. The voltage supervisor circuit is configured to assert a “low-voltage” signal responsive to detecting the output of the voltage supply powering the NVM device dropping below a predetermined value. The controller is configured to write data into the memory array while the “low-voltage” signal is deasserted and to suspend writing data while the “low-voltage” signal is asserted. In response to assertion of the “low-voltage” signal, the controller completes a write cycle/program operation, if pending, and prevents any additional write cycles/program operation(s) during assertion of the “low-voltage” signal.
