Abstract: Data storage devices function by communication between a controller and a memory device over a data bus. The memory device can, at times, be busy. Attempting to communicate with the memory device while the memory device is busy causes delays. Holding back communications when the memory device is not busy causes avoidable delays. Correctly predicting the timing of when the memory device is available will reduce delays. An adaptive prediction timer is used that increases the time between communications if a status check of the memory device returns a busy indication, and decreases the time between communications if the status check returns a not busy indication.

Abstract: A system and method for applying a first level of protection to data in a memory module include identifying a weak wordline from at least one of a plurality of blocks of the memory module. Each of the plurality of blocks includes a plurality of wordlines. The system and method also include determining that the weak wordline is to receive the first level of protection and applying the first level of protection to the weak wordline.

Abstract: A non-volatile memory die includes a plurality of non-volatile memory cells and die control circuitry. The die control circuitry is configured to respond to a received command to access the plurality of non-volatile memory cells by sending a response indicated by the received command together with die variable information. The die variable information includes information not indicated by the received command.

Abstract: The disclosure relates in some aspects to reporting the amount of available physical storage space of a non-volatile memory (NVM) array. A device including an NVM array may send reports regarding the amount of available physical storage space in the non-volatile memory device to a host device or some other suitable apparatus. The amount of available physical storage space takes into account whether any of the physical address blocks of the NVM array have been designated as worn-out. The host device (or other suitable apparatus) may send a report to a user when the amount of available physical storage space is relatively low.

Abstract: A processing device includes an instruction memory to store executable applications that are executable by a target processor, and a compiler. The compiler includes a builder module and a call graph generator. The builder module to build executable applications for the target processor based on a set of instructions. The call graph generator to create a first call graph that indicates a stack usage for each call path of the executable applications. If a first executable application built by the builder module includes a call path that exceeds a stack size constraint of the target processor, the builder module to optimize only functions within the call path that exceeds the stack size constraint in response to the request from the evaluation monitor, and to build a second executable application based on the set of instructions. The second executable application is optimized for stack memory usage of the target processor.

Abstract: There is described a method of managing a flow of data packets in a multiple-processing entity system comprising a plurality of look-up tables adapted to store information associated to actions to be performed on packets received by the system. The method comprises storing, on a per entry basis, in a shadowed entry associated to any table entry being updated, the previous content of said table entry being updated, in association with a table entry version number, for use for managing packets received in the system prior to any update operation. It is thus possible to continue using look-up tables while updating process is being carried out for some or all of the table entries. The solution provides benefits for systems that are limited in space and cost, by use of minimal memory thanks to the storing of small shadowed data instead of full shadowed table.
