    Abstract: A method for managing a memory stack provides mapping a part of the memory stack to a span of fast memory and a part of the memory stack to a span of slow memory, wherein the fast memory provides access speed substantially higher than the access speed provided by the slow memory.

    Abstract: Certain exemplary aspects of the present disclosure are directed towards methods and apparatuses in which logic circuitry generates an error detection code based on user data received from a host, and further generates a first set of check bits, to be written to the non-volatile memory circuit in conjunction with the user data, by combining the error detection code with a hashed data address of the user data. In some embodiments, the check bits associated with the user data providing verification that the user data was written in the appropriate physical block address of the non-volatile memory circuit.

    Abstract: Systems and methods are disclosed for probabilistic aging command sorting, including adjusting an execution order for a command based on a probability of the command reaching a time out threshold. Various example embodiments are directed to selecting a command for execution from a queue of commands awaiting execution, in which the commands have non-uniform attributes influencing their selection and a time limit within which to execute them. In some embodiments, an apparatus may comprise a circuit configured to calculate a first estimated access time to execute a selected command from a command queue, modify the first estimated access time based on a probability of the selected command reaching a time-out age threshold to determine a time out-adjusted access time, and execute the selected command in an order based on the time out-adjusted access time.

    Abstract: Data storage devices may store selected data received from a data source to a buffer memory. The selected data may be copied from the buffer to a non-volatile memory configured for sequential storage. The selected data may then be copied from the buffer to a solid state memory, such as dynamic random access memory. The selected data may be copied from the solid state memory to a main store, such as a magnetic disc memory. If the selected data cannot be found in the solid state memory, the selected data in the non-volatile memory can be copied to the main store.
