Abstract: A non-volatile memory includes physical blocks each including a respective plurality of cells, where each cell is capable of storing multiple bits of data. A controller maintains dynamically resizable pools of physical blocks, including at least a low-density pool in which cells are configured to store fewer bits and a high-density pool in which cells are configured to store more bits. The controller determines whe ther total utilization of physical blocks is less than a low-density pool utilization threshold above which the high-density pool of physical blocks is utilized for storing host write data and additionally identifies cold in-use logical block address (LBA) regions having low total access frequencies. Based on determining the total utilization of physical blocks is less than the low-density pool utilization threshold, the controller performs data placement of data from the cold in-use LBA regions in blocks of the high-density pool.

Abstract: Threshold voltage shift values, or TVS values, are calibrated for a non-volatile memory unit including strings of memory cells organized into memory pages, the memory pages being organized into blocks. The calibration involves a read operation to read a given page of the memory pages, based on given one or more TVS values for the given page. In response to a read failure of the read operation, the calibration determines one or more corrected TVS values based on one or more reference TVS values of one or more reference pages of the memory pages. The calibration subsequently performs a read operation to read the given page based on the one or more corrected TVS values. This calibration exploits TVS values of reference pages to determine corrected TVS values of the failing page, instead of finding appropriate TVS values by repeatedly re-reading the failing page.

Abstract: A secure peer-to-peer streaming media session is initiated in a secure data network based on a secure executable container executed by an endpoint device receiving a request, by an originating entity, for initiating the session with a second network entity having a two-way trusted relationship with the endpoint device in the secure data network via a second network device. The secure executable container: generates a conversation object identifying the second network entity as a participant in the session, and causes secure autonomic synchronization of the conversation object with the second network device; generates a message object and adds a reference to the conversation object; and updates a hypercontent body in the message object with streaming media data received from an executable media source in the endpoint device. The updating causes the second network device to retrieve each update of the streaming media data in the hypercontent body during the session.

Abstract: Provided are a storage device, system, and method for throttling host writes in a host buffer to a storage device. The storage device is coupled to a host system having a host buffer that includes reads and writes to pages of the storage device. Garbage collection consolidates valid data from pages in the storage device to fewer pages. A determination is made as to whether a processing measurement at the storage device satisfies a threshold. A timer value is set to a positive value in response to determining that the processing measurement satisfies the threshold. The timer is started to run for the timer value. Writes from the host buffer are blocked while the timer is running. Writes remain in the host buffer while the timer is running. A write is accepted from the host buffer to process in response to expiration of the timer.

Abstract: A non-volatile memory includes a plurality of cells each individually capable of storing multiple bits of data including bits of multiple physical pages. A controller of the non-volatile memory issues a command to perform a programming pass for a physical page among the multiple physical pages.

Abstract: A controller of a non-volatile memory detects errors in data read from a particular physical page of the non-volatile memory. Based on detecting the errors, the controller performs a read voltage threshold calibration for a page group including the particular physical page and a multiple other physical pages. Performing the read voltage threshold calibration includes calibrating read voltage thresholds based on only the particular physical page of the page group. After the controller performs the read voltage threshold calibration, the controller optionally validates the calibration. Validating the calibration includes determining whether bit error rates diverge within the page group and, if so, mitigating the divergence. Mitigating the divergence includes relocating data from the page group to another block of the non-volatile memory.

Abstract: Secure access recovery to a network device includes encrypting a user password into an encrypted target password using a secret regenerative key, and adding a one-time password seed and the encrypted target password into a secure recovery container, which is stored securely in the network device and a trusted recovery device. In response to a recovery request, a one-time password can be generated using the one-time password seed to retrieve the encrypted target password from the recovery device. A decrypted recovery password is generated based on executing decryption on an input string based on the secret regenerative key. The encrypted target password, retrieved from the secure recovery container in the network device, is decrypted into a decrypted target password based on the secret regenerative key. Secure access is recovered in response to determining the decrypted recovery password matches at least a part of the decrypted target password.
