摘要： A controller for one type of NAND flash memory device that emulates another type of NAND flash memory device. The controller may include a host NAND interface to receive host data from a NAND host device, and a data aggregator for aggregating the host data with complementary data, to thereby create device data that is storable in a device page of an array of NAND flash memory cells of the NAND flash memory device. After creating the device data the controller writes the device data into a device page of the NAND flash memory cells. The controller also includes a data parser to parse host data from device data when data read operations are executed by the controller. If required, the controller uses the data parser to parse complementary data from device data to create device data when data writing operations are executed by the controller.

摘要： A storage module and method for identifying hot and cold data are provided. The storage module can be removable from a host or can be embedded in a host. In one embodiment, a request to store data in a logical block address (LBA) of a memory of the storage module is received. A physical block associated with the LBA is determined, and it is also determined whether the physical block stores hot or cold data. A last-known open block is then selected, wherein the last-known open block is either hot or cold depending on whether the physical block stores hot or cold data. If space is available in the last-known open block, the data is written to the last-known open block.

摘要： A storage device and method for reallocating storage device resources based on an estimated fill level of a host buffer are disclosed. In one embodiment, a storage device receives, from a host device, a rate at which the host device stores data in its buffer and tracks an amount of data that was received from the host device. The storage device estimates a fill level of the buffer at an elapsed time using the rate, the elapsed time, and the amount of data received from the host device over that elapsed time. If the estimated fill level of the buffer is above a threshold, the storage device increases a rate of receiving data from the host device.

摘要： A method and host device for packing and dispatching read and write commands are provided. In one embodiment, a host device receives commands from at least one application, wherein the commands include read commands and write commands. The host device stores the commands in the memory. The host device then selects the read commands from the memory and packs them together but separately from the write commands. The same thing is done for the write commands. The host device then sends the packed read commands and the packed write commands to the storage device. In another embodiment, the host device determines when to send the packed commands to the storage device based on at least one parameter.

摘要： A method is performed in a data storage device that includes a controller coupled to a non-volatile memory. The non-volatile memory includes a group of storage elements. Each storage element is configured to store multiple data bits. Data is sent from the controller to the non-volatile memory and first bits corresponding to a first portion of the data are stored into the group of storage elements during a first write stage. Each storage element of the group of storage elements stores at least one bit of the first bits upon completion of the first write stage. Second bits corresponding to a second portion of the data are sent to a second memory without sending the first bits to the second memory. The second bits are retrieved from the second memory and at least the second bits are stored into the group of storage elements during a second write stage.

摘要： A memory system self-initiates hibernation mode and responds to host commands issued during hibernation within a host protocol timeout period. Hibernation mode is entered after controller state data has been stored and while no host command to the memory system is pending. Power to volatile data storage is diminished during hibernation mode. Upon receiving a host command during hibernation mode, power is restored and a reduced portion of the controller state data is read from non-volatile memory. A removable data storage device or a portable electronic device with embedded data storage may be constructed with such a self-hibernating memory system.

摘要： A method of executing an erasing instruction to erase host data from a flash memory device is provided. The method initiates with receiving from a host device an erase instruction to erase host data from an array of NAND flash memory cells grouped into separately-erasable device blocks, each device block including multiple device pages, the host data being a portion of device data that is stored in a device block. The host data is marked as erased, and a message is sent to the host device indicating that the host data has been erased.
