Abstract: Methods and systems are provided that execute reduced host data commands. A reduced host data command may be a write command that includes or is received with an indication of host data instead of the host data. The reduced host data command may be executed with a Direct Memory Access (DMA) circuit independently of a processor that executes administrative commands. In the execution of the reduced host data command, host data may be generated, metadata may be generated, and the generated host data and/or metadata may be copied into backend memory with the DMA circuit independently of the processor.

Abstract: A method of storing a set of metadata bits associated with each of multiple data words includes combining the set of metadata bits with each of the multiple data words to generate multiple extended data words. The method includes encoding each of the multiple extended data words to generate multiple codewords and puncturing each of the multiple codewords to generate multiple punctured codewords, where in each of the punctured codewords the set of metadata bits is removed. The method includes storing the multiple punctured codewords, transforming the set of metadata bits to generate a set of transformed metadata bits, and storing the set of transformed metadata bits.

Abstract: A non-volatile memory has its cells' thresholds programmed within any one of a first set of voltage bands partitioned by a first set of reference thresholds across a threshold window. The cells are read at a higher resolution relative to a second set of reference thresholds so as to provide additional soft bits for error correction. The reference thresholds of the second set are set up to be non-uniformly distributed on the threshold window so as to provide higher resolution at designated regions. At the same time they are conducive to be read in groups for soft bits to be read bit-by-bit systematically with a simple algorithm and read circuit and using a minimum of data latches. This is accomplished by relaxing the requirement that the first set of reference threshold is a subset of the second set and that the resulting soft bits are symmetrically distributed about the hard bits.

Abstract: Systems and methods for managing a storage device are disclosed. Generally, in a host to which a storage device is operatively coupled, wherein the storage device includes a cache for storing one or more discardable files, a file is identified to be uploaded to an external location. A determination is made whether sufficient free space exists in the cache to pre-stage the file for upload to the external location and the file is stored in the cache upon determining that sufficient free space exists in the cache to pre-stage the file for upload to the external location, wherein pre-stating prepares a file for opportunistically uploading such file in accordance with an uploading policy.

Abstract: A bridge includes a host interface via which data/commands are received from and transferred to a host, and a storage device interface via which data/commands are received from and transferred to a storage device. The bridge also includes one SDPC, a controller and a switching system that is configurable by the controller to connect the protocol converter to the host interface and the storage device interface if the storage device protocol used by the host device differs from the storage device protocol used by the storage device, and to connect the host device interface to the storage device interface, not via the bi¬ directional protocol converter, if the two storage device protocols are the same. The bridge may include two SDPCs, each for converting a different protocol to the host protocol and vice versa, with the switching system being configurable to switch between the two SDPCs. The bridge may omit the SDPC altogether, with the switching system being configurable to switch between connecting (1) the host device interface to the storage device interface, and (2) bypassing the storage device interface.
