Binding a public cloud account and a personal cloud account is described. A pre-approval list indicates that a user's public cloud account and personal cloud account are approved for binding. A copy of the pre-approval list is stored on the personal cloud device; another copy is stored on the public cloud service. The user logs into the public cloud account using a client device. Based on the pre-approval list stored on the public cloud service, the client device obtains information identifying the user's personal cloud account. The personal cloud device verifies the pre-approval of the binding based on the pre-approval list stored on the personal cloud device. The personal cloud device transmits a verification to the public cloud service. Each of the public cloud service and the personal cloud device stores information indicating the binding.

Techniques for implementing a storage system using a personal user device and a data distribution device are disclosed. A personal user device stores a particular content item and transmits the particular content item to a data distribution device for storage. A client device transmits a request for the particular content item to the personal user device. The personal user device determines a characteristic associated with the personal user device, the data distribution device, the client device, and/or the particular content item. Based on the characteristic, the personal user device determines whether to serve the particular content item, or to redirect the client device to the data distribution device to obtain the particular content item. If the client device is redirected, then the client device transmits a request for the particular content item to the data distribution device. The data distribution device transmits the particular content item to the client device.

Implementing a storage system using a personal user device and a data distribution device

A storage system is implemented using a personal user device and a data distribution device. A personal user device stores a particular content item and transmits the particular content item to a data distribution device for storage. A client device transmits a request for the particular content item to the personal user device. The personal user device determines a characteristic associated with the personal user device, the data distribution device, the client device, and/or the particular content item. Based on the characteristic, the personal user device determines whether to serve the particular content item, or to redirect the client device to the data distribution device to obtain the particular content item. If the client device is redirected, then the client device transmits a request for the particular content item to the data distribution device. The data distribution device transmits the particular content item to the client device.

A method includes, in at least one aspect, designating a first region of a memory device for storing data of a first type and first error correcting code (ECC) data; designating a second region for storing data of a second type and second ECC data; receiving the data of the first type; generating the first ECC data for the data of the first type using a first ECC associated with a first ECC protection level; storing the data of the first type and the first ECC data in adjacent locations of the first region; receiving the data of the second type; generating the second ECC data for the data of the second type using a second ECC associated with a second ECC protection level; and storing the data of the second type and the second ECC data in the second region.

A solid-state disk including first and second memories and a wear leveling module. The second memory has a lower write cycle lifetime than the first memory. The wear leveling module: receives logical addresses (LAs) from a host; determines write frequencies respectively for the LAs, where the write frequencies indicate how frequently data is written to the LAs; determines write frequency rankings (WFRs) based on respectively the write frequencies, where each of the WFRs is based on a weighted time-decay average of write counts or an average of elapsed times of write cycles for the corresponding one of the LAs; and for each LA mapped to the first memory, if a corresponding one of the WFRs is greater than a lowest one of the WFRs of (i) the first memory, or (ii) the first and second memories, remaps the LA with the lowest WFR to a different physical address.

A system including filter circuits, a least mean square (LMS) engine, and a gain controller. A first filter circuit includes first taps that receive first coefficients. The first filter circuit filters a digital signal to generate a first filtered signal. One of the first coefficients is constrained. The LMS engine, based on a first input signal and a LMS algorithm, generates the first coefficients. A second filter circuit includes second taps that receive second coefficients. The second filter circuit filters the first filtered signal to generate a second filtered signal. The gain controller adjusts a gain of the digital signal based on a second input signal. The second filter circuit introduces: a difference in gain between outputs of the first and second filter circuits to adjust amplitudes of the first and second input signals; and a sampling phase offset between the outputs of the first and second filter circuits.

A storage drive including a first and second memories and a controller. The second memory has a write cycle lifetime that is less than a write cycle lifetime of the first memory. Each of the first and second memories includes solid-state memory. The controller: determines a write frequency for a first logical address; and based on the write frequency, determines a write frequency ranking for the first logical address. The write frequency ranking is based on a weighted time-decay average of write counts or an average of elapsed times of write cycles. The controller also: determines whether the write frequency ranking is greater than a lowest write frequency ranking of logical addresses of the first memory; and if the write frequency ranking of the first logical address is greater, maps the logical address with the lowest write frequency ranking in the first memory to the second memory.
