20140181373 | Persistent Storage Device with NVRAM for Staging Writes - A persistent storage device includes both persistent storage, which includes a set of persistent storage blocks, and NVRAM, and in particular a set of NVRAM blocks. The persistent storage device also typically includes a storage controller. The persistent storage device, in addition to responding to commands to write data directly to and to read data directly from persistent storage blocks is also configured to write data to specified NVRAM blocks (e.g., specified by a host NVRAM write command) and to transfer data from a specified NVRAM block to a specified persistent storage block. As a result, multiple writes to a particular persistent storage block can be replaced with multiple writes to an NVRAM block and a subsequent single write to the particular persistent storage block. This reduces the number of writes to persistent storage and also reduces the number of corresponding block erase operations. | 06-26-2014 |
20140189211 | Remapping Blocks in a Storage Device - In the present disclosure, a persistent storage device includes both persistent storage, which includes a set of persistent storage blocks, and a storage controller. The persistent storage device stores and retrieves data in response to commands received from an external host device. The persistent storage device stores a logical block address to physical address mapping. The persistent storage device also, in response to a remapping command, stores an updated logical block address to physical block address mapping. | 07-03-2014 |
20140189264 | Reads and Writes Between a Contiguous Data Block and Noncontiguous Sets of Logical Address Blocks in a Persistent Storage Device - In the present disclosure, a persistent storage device includes both persistent storage, which includes a set of persistent storage blocks, and a storage controller. The persistent storage device stores and retrieves data in response to commands received from an external host device. The persistent storage device stores data, from a contiguous data block, to two or more sets of logical address blocks in persistent storage. The persistent storage device also retrieves data, corresponding to a contiguous data block, from two or more sets of logical address blocks in persistent. In both instances, the two or more sets of logical address blocks in persistent storage, in aggregate, are not contiguous. | 07-03-2014 |

20120324276 | INTELLIGENT BIT RECOVERY FOR FLASH MEMORY - A method and system intelligent bit recovery is provided. The intelligent bit recovery determines which bits are toggling, and examines a subset of the potential bit patterns to determine which in the subset of potential bit patterns is valid. The subset is a fraction of the potential bit patterns, and is based on an understanding of the flash memory and the problems that may cause the toggling bits. The intelligent bit recovery may analyze at least one aspect of the flash memory to identify which problem is potentially causing the toggling bits, and to select the subset of potential bit patterns as solutions for the determined problem. Or, the intelligent bit recovery selects potential bit patterns for multiple potential problems. In either way, the subset of potential bit patterns examined by the intelligent bit recovery is a small fraction of the entire set of potential bit patterns. | 12-20-2012 |
20120324277 | SYSTEM AND METHOD FOR DETECTING COPYBACK PROGRAMMING PROBLEMS - Methods and systems are disclosed herein for detecting problems related to copyback programming. After the copyback data is read into the internal flash buffer, a part of the copyback data stored in the internal flash buffer (such as spare data) is analyzed to determine whether there are any errors in a part of the copyback data read. The analysis may be used by the flash memory in one or more ways related to the current copyback operation, subsequent copyback operations, subsequent treatment of the data in the current copyback operation, and subsequent treatment of the section in memory associated with the source page. | 12-20-2012 |
20130265841 | Immunity Against Temporary and Short Power Drops in Non-Volatile Memory - A mechanism is presented memory circuits, such a NAND-type flash memories, to autonomously protect themselves from temporary and short power drops. A detection mechanism looks for the supply voltage to drop below a function voltage for a period of time. When such an event occurs, a suspend mechanism is activated, and after completing the last micro-operation (such as a program pulse) the memory freezes. When power is again stable at an operational level, the suspended operation is resumed. The memory controller can then be notified upon occurrence of such voltage drop by polling a special status bit. Examples of how the pausing can be implemented include altering of clock signals and suspending sub-phases of larger operations. | 10-10-2013 |
