摘要： A data storage system using flash storage maintains a status indicator corresponding to data written into the flash storage. The status indictor of the data indicates whether a disruption, such as a power disruption or a device disconnection, occurred when the data was being written into the flash storage. The data storage system determines whether the data may be corrupted based on one or more of the status indictors. The data storage system may make this determination at a selected time or after a power-up of the data storage system. If the data is determined to possibly be corrupted, the data storage system may optionally discard the corrupted data from the flash storage or flag the corrupted data for future removal.

摘要： A process of data storage utilizing a data management system that transfers data between a host system and multiple storage devices through multiple channels. The data management system receives data from the host system and writes the data as data segments to the multiple storage devices. Each data segment may comprise one sector, more than one sector, or a portion of a sector, depending on the embodiment. The data segments are transferred to and from the multiple storage devices in parallel fashion while the data in each data segment is transferred to its corresponding data storage device sequentially. The data management system reassembles data segments received from the data storage devices and sends the data to the host system.

摘要： A flash storage device having improved write performance is provided. The device includes a storage block having a plurality of physical pages and a controller configured to allocate subsets of the plurality of physical pages to a plurality of logical addresses, respectively, and to write data to the plurality of physical pages. Each of the subsets of physical pages includes more than one physical page. Upon receiving a first write request for one of the logical addresses, data from the first write request is written to a first physical page of the physical pages allocated to the logical address. Upon receiving a second write request for one of the logical address, the data from the second write request is written to a second physical page allocated to the logical address and the first physical page allocated to the logical address is invalidated.

摘要： A flash storage device includes flash storage units that are purged in response to a condition or command. A flash controller interface receives a command for purging the flash storage device and provides a purge command to flash controllers in the flash storage device. Alternatively, the flash storage device detects a condition in response to which the flash controller interface provides a purge command to the flash controllers. Each flash controller independently erases a flash storage unit in response to receiving the purge command, by writing a pattern of data to the flash storage unit, such that the flash storage units are purged substantially in parallel with each other.

摘要： A flash storage device having improved write performance is provided. The device includes a storage block having a plurality of physical pages and a controller for mapping the plurality of physical pages to a plurality of logical addresses and for writing data to the plurality of physical pages. When updating data previously written to one of the plurality of logical addresses, the controller is configured to write the updated data to a second physical page which is mapped to the logical address. Each of the logical addresses may be associated with a pointer field, which is for storing a pointer value indicating the invalidity of a physical page and/or the location of another physical page.

摘要： A flash storage device includes flash storage units that are erased in response to a condition or command while allowing the flash storage device to be used subsequent to the erase. A flash controller interface receives a command for erasing the flash storage device and provides an erase command to flash controllers in the flash storage device. Alternatively, the flash storage device detects a condition in response to which the flash controller interface provides an erase command to the flash controllers. Each flash controller independently erases a flash storage unit in response to receiving the purge command such that the flash storage units are erased substantially in parallel with each other and the erase operations overlap. Subsequent to the erase, certain control data is reconstructed to allow subsequent use of the flash storage device.
