摘要： A memory controller, in one embodiment, includes a command translation data structure, a front end and a back end. The command translation data structure maps command operations to primitives, wherein the primitives are decomposed from command operations determined for one or more memory devices. The front end receives command operations from a processing unit and translates each command operation to a set of one or more corresponding primitives using the command translation data structure. The back end outputs the set of one or more corresponding primitives for each received command operation to a given memory device.

摘要： A system for selecting a subset of issued flash storage commands to improve processing time for command execution. A plurality of ports stores a first plurality of command identifiers and are associated with the plurality of ports. Each of the first plurality of arbiters selects an oldest command identifier among command identifiers within each corresponding port resulting in a second plurality of command identifiers. A second arbiter makes a plurality of selections from the second plurality of command identifiers based on command identifier age and the priority of the port. A session identifier queue stores commands associated with the plurality of selections among other commands forming a third plurality of commands. A microcontroller selects an executable command from the third plurality of commands for execution based on an execution optimization heuristic. After execution of the command, the command identifier in the port is cleared.

摘要： The wear-leveling techniques include discovering a persistent state of one or more memory devices, or building and caching persistent state parameters for each logical unit of a given memory device if a persistent state is not discovered for a given memory device. The techniques may also include processing memory access commands utilizing the cached persistent state parameters. When processing memory access commands, the logical block address and length parameter of a logical address of a command may be translated to a plurality of physical addresses for accessing one or more memory devices, each physical address includes a device address, a logical unit address, a block address, and a page address, wherein the block address includes one or more interleaved address bits.

摘要： An error locator unit for correcting two bit error. The error locator unit includes a plurality of operational units, a normalized basis transform unit, and a conversion unit. The plurality of operations units calculates coefficients of the polynomial based on the generated syndromes in a first basis of a Galois Field. Operating on the coefficients produces a root definition value vector in the first basis. The normalized basis transform unit transforms the root definition value vector to a normal basis to produce a plurality of roots. The conversion unit converts the plurality of roots to the first basis. A scaling factor calculated based on the coefficients is applied to the output of the conversion unit to produce a plurality of scaled roots for said polynomial in the first basis. The plurality of scaled roots is added to produce error locations for the polynomial.
